Pickled plates (made from high-quality hot-rolled sheets as raw materials, after the pickling unit has removed the oxide layer, trimmed, and finished), the surface quality and usage requirements (mainly cold bending or stamping performance) are between hot-rolled plates and cold-rolled plates. The intermediate product between rolled plates is an ideal substitute for some hot-rolled plates and cold-rolled plates. Compared with hot-rolled plates, the main advantage of pickled plates is) good surface quality, because hot-rolled pickled plates remove the surface Oxidized iron scale improves the surface quality of steel and facilitates welding, oiling and painting. ) has high dimensional accuracy. After flattening, the plate shape can be changed to a certain extent, thereby reducing the unevenness deviation. ) improves the surface finish and enhances the appearance. ) can reduce environmental pollution caused by dispersed pickling by users. Compared with cold-rolled plates, the advantage of pickled plates is that it allows users to effectively reduce procurement costs while ensuring surface quality and usage requirements. At present, many companies have higher and higher requirements for high performance and low cost of steel. With the continuous advancement of steel rolling technology, the performance of hot-rolled sheets is approaching that of cold-rolled sheets, making it technically possible to replace cold with heat. It can be said that pickled plates are a product with a relatively high performance-price ratio between cold-rolled plates and hot-rolled plates, and have good market development prospects. However, from the current point of view, the use of pickling plates in various industries in my country has just started. The production of professional pickling plates began when Baosteel's pickling production line was put into operation. The pickling plate market is mainly reflected in the following four aspects: replacing cold rolling, replacing hot rolling, replacing imports and replacing small pickling. Among them, import substitution and small pickling are actually existing markets, and the market is limited and it is impossible to completely replace them. With the rapid development of automobile, machinery, light industry and other industries, enterprises are facing huge pressure brought by market competition, and their requirements for product cost and product quality are increasing day by day. Pickling plates can completely replace some cold steel products with their high cost performance. Plates and hot plates will gradually be recognized by users.
The main processes of hot-rolled pickled plates include laser welding, stretch straightening, turbulent pickling, online smoothing, trimming, online oiling, etc.
Baosteel's pickling specifications are generally *. Products include low, medium and high strength stamping steel, automobile structural steel, etc., which are mainly delivered in the form of steel coils. Features of the process: Use hydrochloric acid to remove the iron oxide scale on the hot-rolled steel plate to obtain a beautiful and smooth surface.
Product Features
To reduce costs, using pickled plates instead of cold-rolled plates can save costs for enterprises.
, Good surface quality. Compared with ordinary hot-rolled plates, hot-rolled pickled plates remove surface iron scale, improve the surface quality of the steel, and facilitate welding, oiling and painting.
. High dimensional accuracy. After flattening, the plate shape can be changed to a certain extent, thereby reducing the unevenness deviation.
, improve the surface finish and enhance the appearance effect.
Main uses
The main uses of hot-rolled pickling in the automotive industry are as follows: automotive chassis systems, including frames, sub-frames, etc. Wheels, including rims, wheel radials, etc. Cabin panel. Cabin panels are mainly the cabin floors of various trucks. Other stamped parts include anti-collision bumpers, brake casings and other small internal automotive parts.
The machinery industry (excluding automobiles) mainly includes textile machinery, mining machinery, fans and some general machinery.
, light industrial home appliances, mainly used to manufacture compressor casings, brackets, water heater liner, etc. Chemical oil barrel.
, other bicycle parts, various welded pipes, electrical cabinets, highway guardrails, supermarket shelves, warehouse shelves, fences, iron ladders and stamping parts of various shapes.
