Automobile Industry Hot-rolled pickling and oil-coated sheet is a new type of steel needed by the automotive industry. Its better surface quality, thickness tolerance, and processing performance can replace body panels and auto parts that were previously produced with cold-rolled sheets, thereby reducing raw material costs. The cost is about 10%. With the development of the economy, the production of automobiles has also increased significantly, and the use of plates has been continuously increased. The original design of the parts and components of many models in the domestic automobile industry requires the use of hot-rolled pickled plates.Agricultural Motorcycle The agricultural vehicle manufacturing industry is developing rapidly. Among them, the agricultural vehicle industry in the Shandong market is developing rapidly. The overall demand for cold and hot plates in the whole year is about 400,000 tons. Many agricultural vehicle manufacturers are willing to use acid-washed plates instead of cold plates in order to reduce costs. Among them The parts that can "replace cold with heat" are mainly the cab's inner panel and windshield, and the required specifications are mainly 0.8-1.5×1000-1250mm. The wheels of motorcycles can also use acid-washed plates. Motorcycle wheels generally use 2.0mm cold plates. Due to the high cost and the difficulty of purchasing thick cold plates, some manufacturers once switched to hot-rolled plates. However, hot-rolled plates have the problem of poor surface quality, which is difficult to meet the needs of manufacturers. . The use of pickling plates can meet the dual requirements of users on cost and quality.Machinery Industry Hot-rolled pickled sheets are mainly used in textile machinery, mining machinery, fans and some general machinery. Such as the manufacture of compressor housings and upper and lower covers for household refrigerators and air conditioners, pressure vessels and mufflers for power compressors, and bases for screw air compressors. Among them, household refrigerators and air-conditioning compressors use the most acid-washed boards, which have high requirements on the deep-drawing performance of acid-washed boards. The materials are mainly SPHC, SPHD, SPHE, SAPH370, the thickness range is 1.0-4.5mm, and the required specifications are 2.0-3.5mm. Relevant data show that in the first half of the year, the hot-rolled pickling plates required for refrigerator compressors and air-conditioning compressors were 80,000 tons and 135,000 tons respectively. The fan industry mainly uses cold-rolled sheets and hot-rolled sheets. Hot-rolled pickled sheets can be used instead of cold sheets to manufacture impellers, casings, flanges, mufflers, bases, platforms, etc. of blowers and fans.Other Industry Other industry applications mainly include bicycle parts, various welded pipes, electrical cabinets, highway guardrails, supermarket shelves, warehouse shelves, fences, water heater liner, barrels, iron ladders and stamping parts of various shapes. With the continuous development of the economy, zero-part processing has spread all over the industry, and processing plants have sprung up rapidly, which greatly increases the demand for plates and also increases the potential demand for hot-rolled pickled plates.
