• How to protect driving safety with surround view monitors?

    AVM is a panoramic image system, namely Automotive Around View Monitor/Surround View Camera.
    It is another great helper for safe driving and can realize driving without blind spots.


    Images are captured through wintoplens multiple ultra-large wide-angle fisheye lenses, and then the captured images are distorted and spliced through data processing to form surrounding images.

    It is mostly used in automobile systems to provide the driver with a bird's-eye view of the surroundings of the car body, eliminate the driver's blind spots, and provide effective visual assistance when parking.

    In fact, surround view systems can be divided into monocular, binocular and multi-view systems.

    Among them, the monocular and binocular systems must establish a virtual coordinate system while the vehicle is moving to draw a panoramic image to guide parking. The multi-view system can directly guide parking.

    ⁉ So how many cameras are needed for the entire operation process?

    ✔ 360-degree panoramic camera, 360-degree panoramic imaging system, 360-degree panoramic parking system, 360-degree panoramic vision system, and 360-degree panoramic reversing system simultaneously collect images around the vehicle through 4 ultra-wide-angle cameras installed on the front, rear, left, and right of the vehicle.

    ✔ Through Pujieli's proprietary "real-time image distortion restoration docking technology", the image is processed through distortion restoration, perspective conversion, image splicing, and image enhancement, and finally forms a seamless and complete panoramic bird's-eye view of the car's surroundings.

    ✔ The system can not only display a panoramic view, but also display a single view in any direction at the same time; the driver can accurately read the location and distance of obstacles by matching the ruler lines.



     

  • What is the technical principle of car mounted surround lenses?

    The technical principles of wintoplens car mounted surround lenses mainly include the following aspects:

    Lens design: Car surround photography typically uses multiple cameras, which are distributed around the vehicle to provide a more comprehensive view. The design of a lens needs to consider various factors, such as the focal length, aperture, angle of view, etc., in order to obtain high-quality images during the shooting process.


    Shooting method: The shooting method for car surround lenses includes two aspects: hardware and software. Hardware includes cameras, brackets, power supplies, etc. It is necessary to choose high-quality equipment to ensure the stability of shooting. In terms of software, post production requires professional image processing software to fuse and concatenate images captured by multiple cameras to form the final surround lens image.


    Post processing: After the shooting is completed, it is necessary to perform post processing on images from multiple cameras in order to fuse them into a complete image.



     

  • Material selection should be based on the characteristics of the medium.

    What medium properties should be considered for material selection?

     

    1. Acetic acid is highly corrosive, and ordinary steel is prone to corrosion. Stainless steel is a good material for resisting acetic acid.

     

    2. For high-temperature and dilute acetic acid steam, molybdenum-containing stainless steel chemical pumps can be selected. Under harsh requirements, high-alloy stainless steel or fluoroplastic pumps can be used.

    3. For sodium hydroxide solutions with a concentration of 30% and at temperatures below 80°C, steel is widely used.

     

    4. For high-temperature alkali solutions, titanium and titanium alloys or high-alloy stainless steels are often used.

     

    5. The corrosion of ammonia and ammonium hydroxide is slight, and most metals and non-metals are suitable.

    6. When using ordinary steel in salt water, paint protection is required. 316 stainless steel is a better choice.

     

    7. Media such as alcohols and ketones are basically non-corrosive, but attention should be paid when selecting rubber seals.

     

    8. The selection of materials for sulfuric acid, hydrochloric acid and nitric acid needs to be considered separately according to factors such as concentration and temperature.

     

    In our company, the selection of pumps is generally divided into two categories:

    Metal pumps are suitable for alkaline media, and the materials include 304, 316, 316L and 2205. Fluoroplastic pumps are suitable for acidic media, with the material F46 (for temperatures below 80 °C) and PFA (for temperatures above 80 °C, with a maximum temperature of 120 °C). These two types of pumps are the main products of Anhui Shengshi Datang

  • Unveiling the Alternative Names for Webbing Slings A Comprehensive Guide

    Webbing slings, also known by other names, are an essential tool in various industries for lifting and securing heavy loads. These flexible and durable devices offer numerous advantages and come in different configurations. In this blog post, we will explore the alternative names used to refer to webbing slings, shedding light on the terminology associated with these versatile lifting solutions.

    One commonly used alternative name for webbing slings is "web slings." This term emphasizes the fact that these slings consist of a woven webbing material, typically made of polyester or nylon. The webbing's strength and flexibility enable safe and efficient lifting operations.

    Webbing slings are also commonly called "lifting straps." This name emphasizes their primary function of lifting heavy objects safely. Lifting straps can be wrapped around or attached to the load, providing a secure connection point for lifting equipment, such as cranes or forklifts.

    As polyester material is frequently used in the construction of webbing slings, they are sometimes referred to as "polyester slings." Polyester offers excellent strength, resistance to abrasion, and durability, making it ideal for lifting and load securing tasks.

    Another alternative name for webbing slings is "nylon slings." Nylon is another popular material used in the manufacturing of webbing slings due to its high strength-to-weight ratio and exceptional resistance to chemicals and UV radiation. Nylon slings are known for their ability to stretch and absorb shock, ensuring secure and reliable operation.

    In rigging applications, webbing slings are often referred to as "rigging slings." Rigging slings are used for various purposes, such as lifting, supporting, or securing loads during construction or installation projects. The term "rigging" denotes the process of setting up and maintaining the equipment necessary for lifting and moving heavy loads.

  • Webbing Sling Damage Identifying and Addressing Common Issues

    Webbing slings are valuable lifting tools used in various industries for safe and efficient material handling. However, like any equipment, webbing slings can be susceptible to damage over time due to regular use, environmental conditions, and improper handling. In this blog post, we will delve into common types of webbing sling damage, their causes, and provide insights into how to identify and address these issues to ensure optimal safety and performance.

    Abrasion damage occurs when the webbing material rubs against rough surfaces, edges, or sharp objects. Signs of abrasion include frayed edges, thinning of the webbing, or worn-out areas. To mitigate abrasion, it is essential to inspect slings regularly for signs of wear and use protective sleeves or edge protectors when lifting loads with rough or sharp surfaces.

    Webbing slings can be cut or punctured by sharp objects, such as metal edges, nails, or protruding components. These damages weaken the sling's strength and compromise its lifting capacity. Inspecting slings before each use and removing any debris or sharp objects from the lifting area helps prevent cutting and puncture damage. Additionally, using appropriate padding or protective materials can provide an extra layer of protection.

    webbing sling

    Exposure to ultraviolet (UV) rays from sunlight can cause degradation of the webbing material over time. UV damage is often characterized by discoloration, brittleness, or loss of flexibility in the sling. Storing webbing slings in a cool, dry place away from direct sunlight when not in use, or utilizing UV-resistant sleeves or covers, can help minimize UV degradation.

    Contact with corrosive chemicals, solvents, or acids can deteriorate the webbing material and compromise its integrity. It is crucial to assess the chemical environment and use appropriate chemical-resistant slings when handling hazardous substances. Regular cleaning and maintenance of the slings are also necessary to remove any chemical residues.

    Exceeding the working load limit (WLL) or safe working load (SWL) of a webbing sling places excessive stress on the material, leading to overloading damage. Signs of overloading include elongation of the webbing, deformations, or even complete failure. It is essential to understand and adhere to the specified WLL and SWL, ensuring that the load is within the sling's capacity.

  • What’s the Difference Between Webbing and Slings?

    When discussing lifting and rigging equipment, people often confuse the terms webbing and slings. While they are closely related, they refer to different things. In this article, we’ll explain the differences in simple terms to help you better understand their roles in lifting operations.

    Webbing is a type of woven fabric made from synthetic materials such as polyester, nylon, or polypropylene. It is strong, lightweight, and flexible. Webbing is used as a raw material in many industries – not just for lifting, but also for products like seat belts, backpacks, and safety harnesses.

    In the lifting industry, webbing is commonly used to make slings. However, webbing by itself is not a complete lifting tool; it must be sewn, shaped, and labeled to become a finished product.

    A sling is a complete lifting tool designed to safely lift and move heavy loads. Slings can be made from different materials, such as synthetic webbing, wire rope, or chain. When a sling is made from webbing, it’s called a webbing sling.

    Webbing slings are available in flat or round designs, and they are clearly marked with a label that shows the working load limit (WLL), safety factor, and compliance with international standards like EN 1492-1.

    The main difference is that webbing is the material, and a sling is the final product. You can think of webbing as the fabric, and the sling as the finished lifting equipment. Webbing is not used directly for lifting until it is processed and turned into a certified sling.

    Many people casually refer to “webbing” when they mean “webbing sling,” which leads to confusion. But when safety is involved, it’s important to use the correct terminology and ensure that you are using equipment that has been tested and certified for lifting.

  • 2024 Second Half of the Year Import Iron Ore Continues to Maintain a Strong Supply and Weak Demand Pattern

     

    Import Iron Ore Market Outlook for the Second Half of 2024

    The first half of 2024 witnessed a fluctuating trend in imported iron ore prices, which initially declined, then rebounded, and finally fell again, ending the period lower than at the beginning, reflecting a slight overall decrease. As of June 28, the 62% Australian fines futures price index stood at $106.6 per dry metric ton, a decrease of 25.45% from the beginning of the year, while the 62% port spot price index was at 107.79 yuan/ton, down by 23.06% from the start of the year. The port spot price drop was less than that of the futures, leading to varying degrees of expansion in import profits for different grades. Concurrently, the Shanghai rebar price was 3480 yuan/ton, with a 13% decrease from the beginning of the year, showing that the finished product price drop was less than that of iron ore, indicating a weaker ore and stronger materials market situation. The basic supply and demand situation for iron ore in the first half of the year was characterized by a strong supply and weak demand pattern.

    Price Review

    The iron ore price in the first half of 2024 traced an inverted "N" shape, with a general downward trend, where the iron ore price drop was greater than that of the finished products. The 62% Australian fines index recorded a total drop of 25.45%, while the Shanghai rebar price saw a total decrease of 13%. As of June 28, the 62% Australian fines index was at $106.6 per dry metric ton, the 62% port spot index was at 107.79 yuan/ton, and the Shanghai rebar price was at 3480 yuan/ton.

    Phase 1: January 2 to April 5

    During this period, the 62% Australian fines index fell from the highest annual price of $143 per dry metric ton to the lowest of $97.45 per dry metric ton, a drop of 32%. The iron ore price repeatedly fell due to the dual impact of supply exceeding expectations and demand recovery not meeting expectations. Additionally, the slow pace of resumption of production and work in the terminal real estate and infrastructure sectors led to negative feedback from finished products to raw materials, causing iron ore prices to fall from the highest level of the year to the lowest.

    Phase 2: April 5 to May 22

    The 62% Australian fines index rebounded from $97.45 per dry metric ton to $122.45 per dry metric ton, a rebound of 26%. Macroeconomic benefits and the release of real estate relaxation policies led to a significant improvement in terminal demand, with finished products maintaining a reduction. On the demand side for iron ore, pig iron maintained an upward channel, market sentiment improved, trading activity increased, and iron ore prices rebounded.

    Phase 3: May 22 to June 28

    From $122.45 per dry metric ton, the 62% Australian fines index adjusted to $106.6 per dry metric ton, an adjustment of 13%. At the end of May, the State Council mentioned the strict implementation of steel capacity replacement, and the continuation of crude steel production control in 2024, leading to a decline in iron ore prices. Entering June, with a reduction in macroeconomic good news and the iron ore trading logic gradually shifting to a weak fundamental, coupled with the obvious seasonal off-season characteristics of terminal demand, iron ore prices fell further.

    Fundamental Review

    Supply: Increased Production in the First Half of the Year, Slow Recovery of Overseas Demand

    In the first half of 2024, the total global iron ore shipments amounted to 786 million tons, an increase of 34.78 million tons year-on-year, an increase of 4.6%. Among them, the shipments of Australian iron ore in the first half of the year were 466 million tons, a decrease of 100,000 tons year-on-year, while the shipments from Brazil were 178 million tons, an increase of 11.75 million tons year-on-year, and shipments from other countries were 143 million tons, an increase of 23.14 million tons year-on-year.

    The reasons for this situation mainly lie in: the Australian mines were affected by weather and accidents in the first half of the year, coupled with the new production projects in Australia not reaching the expected capacity; Brazil was relatively less affected by weather, and the mines increased capital expenditure on facility upgrades and maintenance, helping to increase production and shipments; the impact of accidents and geopolitical conflicts on non-mainstream countries has relatively weakened, with Ukraine, South Africa, and India contributing significantly to the increase.

    Demand: Gradual Recovery of Pig Iron Production in the First Half of the Year, Steel Mills Continue Low Inventory Strategy

    According to the Mysteel 247 blast furnace pig iron data, the total pig iron production in the first half of the year reached 415 million tons, a decrease of 14.46 million tons year-on-year, a drop of 3.36%, with an average daily pig iron production of 2.2821 million tons/day, a decrease of 92,500 tons/day year-on-year. It is clear that this year's pig iron production has been relatively weak compared to the same period last year, mainly due to poor performance in the downstream demand side. The inventory of finished products only began to decrease in mid-March this year, later than most years. At the same time, the increase in inventory pressure has led to increased losses for many steel mills, and the frequency of blast furnace maintenance has increased. Compared with the decline in crude steel in the first half of the year, it was found that the decline in pig iron was higher than that of crude steel, largely due to a significant recovery in scrap steel consumption this year.

    Inventory: Continuous Accumulation of Port Iron Ore Inventory in the First Half of the Year

    In the first half of 2024, the port inventory of imported ores first accelerated to a high level compared to the same period in the past three years, and then fluctuated at a high level. This year, the global iron ore supply and the annual comparison of China's iron ore arrivals have maintained a large increase, while pig iron production has been relatively weak year-on-year, so the port iron ore inventory level has expanded year-on-year in January-March, and from April to June, it has shown a continuous high level contrary to the trend of the previous two years.

    Outlook

    Overseas Supply

    According to the seasonal pattern, the iron ore shipments in the second half of each year are higher than in the first half. Based on historical data, the second half of 2021 increased by 38.533 million tons compared to the first half, the second half of 2022 increased by 55.696 million tons, and the second half of 2023 increased by 75.493 million tons. This seasonal characteristic will continue this year. Considering the pace of new iron ore production projects globally and the annual sales and shipment targets of mines, it is expected that the iron ore shipments in the second half of this year will be 60.154 million tons higher than in the first half.

    Domestic Supply

    In the first half of the year, the domestic concentrate production was affected by previous accidents and weakened. Except for the Shanxi region, which is unlikely to resume production this year, some mines in Hebei have started to resume work. There were limited new production projects in the first half of the year, with a year-on-year increase of about 4.3 million tons in domestic concentrate production from January to May. In the second half of the year, despite the impact of winter mining difficulties and other factors, it is expected that some suspended enterprises will resume normal production, and there will be new production projects in the second half of the year. In summary, it is expected that there will be an increase of 2 million tons in domestic concentrate content in the second half of the year.

    Domestic Demand

    In the first half of the year, China's pig iron production decreased by 14.45 million tons year-on-year. For the calculation of iron ore demand in the second half of the year, four aspects need to be considered: first, the possibility of crude steel control policies being implemented in various regions within the year; second, the lack of domestic real estate policy drive; third, local efforts to resolve debt risks, and the slowdown in the development progress of infrastructure projects; finally, the United States, the European Union

The balance of market supply and demand was disrupted, and production enterprises made production adjustments to cope with the current market conditions. Many companies have expanded their business to the high-temperature alloy field from 2020 to 2023. The output of high-temperature alloy steel of key Chinese enterprises was 15,900 tons, 22,300 tons, and 26,200 tons from 2020 to 2022, with a compound annual growth rate of 28.16% in the past three years. The global high-temperature alloy market size reached 38.239 billion yuan in 2023 and is expected to reach 56.767 billion yuan by 2029, indicating significant growth in the high-temperature alloy market in the coming years. Let's briefly understand the current situation of the high-temperature alloy market.

    Definition of High-Temperature Alloy

    High-temperature alloys are a class of metal materials based on iron, nickel, and cobalt that can work for a long time at temperatures above 600°C and under certain stress; they have high-temperature strength, good oxidation resistance, corrosion resistance, good fatigue performance, fracture toughness, and other comprehensive performance. High-temperature alloys have a single austenite structure and exhibit good structural stability and reliability at various temperatures. Due to the above performance characteristics and the high degree of alloying, high-temperature alloys are also known as "superalloys" and are widely used in aviation, aerospace, petroleum, chemical industry, and naval vessels. Based on the matrix element, high-temperature alloys are divided into iron-based, nickel-based, and cobalt-based high-temperature alloys. Iron-based high-temperature alloys can generally only reach temperatures of 750-780°C, while for heat-resistant parts used at higher temperatures, alloys based on nickel and refractory metals are adopted. Nickel-based high-temperature alloys hold a particularly important position in the field of high-temperature alloys, widely used to manufacture the hottest parts of aviation jet engines and various industrial gas turbines.

    Price Trend Tracking

    Looking back at the price trend of high-temperature alloys in the past two months, as of July 9th, the price of N08810 material from Anhui Fukai Resources was reported at 66,000 yuan/ton, a cumulative drop of 15,000 yuan/ton; the price of N08825 material was reported at 98,000 yuan/ton, a cumulative drop of 13,000 yuan/ton; the price of N10276 material was reported at 217,000 yuan/ton, a cumulative drop of 24,000 yuan/ton. It can be seen that high-temperature alloy resources are also showing a weakening trend, but even if the price weakens, the demand for materials such as N08810, N08825, and N10276 still shows a steady growth.

    Features of High-Temperature Alloys

    Excellent High-Temperature Strength: The ability to maintain high mechanical strength in high-temperature environments, ensuring the reliability of the material under extreme conditions.

    Good Oxidation and Hot Corrosion Resistance: The ability to resist the erosion of oxidation and hot corrosion, extending the service life of the material.

    Good Fatigue Resistance and Fracture Toughness: Possessing excellent anti-fatigue and fracture toughness, ensuring the safety and stability of the material during long-term use.

    Sensitivity to Hot Working Processes: The microstructure of the alloy is very sensitive to hot working processes, requiring precise control of heat treatment processes to obtain the best performance and part quality.

    Domestic High-Temperature Alloy Market Situation

    The current situation of the domestic high-temperature alloy market is characterized by a large supply-demand contradiction but has huge development potential.
