Pickling plate, pickled steel board is a high-quality hot-rolled sheet as raw material, by the acid washing unit to remove the oxidation layer, cutting edges, finishing, surface quality and use requirements (mainly cold bend molding or stamping performance) between hot-rolled plate and cold-rolled plate intermediate products, is an ideal alternative to some hot-rolled plate and cold-rolled plate. Compared with hot-rolled plate, the advantages of acid wash plate mainly lie in: 1) the surface quality is good, because hot-rolled pickling plate removes the surface iron oxide, improves the surface quality of steel, easy to weld, oil and paint. 2) High dimensional accuracy, flat, can make a certain change in the plate type, thereby reducing unevenness of the deviation. 3) Improves surface finish and enhances appearance. 4) Can reduce the user dispersion of acid washing caused by environmental pollution.
Compared with cold-rolled plate, the advantage of pickling plate is to make the user effectively reduce the procurement cost under the premise of ensuring the surface quality requirements. At present, many enterprises on the high performance of steel, low cost put forward higher and higher requirements. With the continuous progress of rolling technology, the performance of hot-rolled sheet is approaching the cold-rolled plate, so that "hot-cold" can be achieved technically. Now the mainstream market grades are SPHC, SPHD, SAPH440, QSTE380TM, QSTE420, QSTE460, QSTE340, QSTE500.
Hot-rolled pickling is mainly used in the automotive industry as follows: automotive chassis systems, including girders, sub-beams, etc. Wheels, including rims, wheel radiation, etc. Cab board. Carrier plates, mainly the carrier floors of various trucks. Other stamping parts, including anti-collision bumpers, brake compartments and other small parts of the interior of the car, machinery industry (excluding automobiles) mainly includes textile machinery, mining machinery, wind turbines and some general machinery, light industrial appliances, mainly used in the manufacture of compressor housing, brackets, water heater guts, chemical oil drums, etc., other bicycle parts, various welding pipes, electrical cabinets, highway guardrails, supermarket shelves, warehouse shelves, fences, iron ladders and various shapes of punching parts.
The company's main co-production areas are: Baosteel, Ansteel, Masteel, Bensteel, Wusteel, Yansteel, Baosteel, Tangsteel, Yansteel,Jisteel, Pansteel, Liusteel and so on.
