Pickling plate is a high quality hot rolled sheet as raw material, after removing oxide layer, cutting edge and finishing by pickling unit, surface quality and use requirements (mainly cold bending forming or stamping performance) between hot rolled plate and cold rolled plate, is an ideal replacement product for part of hot rolled plate and cold rolled plate.

Compared with the hot rolled plate, the advantages of pickling plate mainly lie in :1. The surface quality is good, because the hot rolled pickling plate removes the surface oxide sheet, improves the surface quality of steel, and is convenient for welding, oiling and painting. 2, high dimensional accuracy, after leveling, can make the plate type change, so as to reduce the deviation of uneven degree. 3, improve the surface finish, enhance the appearance effect. 4, can reduce user dispersed pickling caused by environmental pollution. Compared with cold-rolled sheet, the advantage of pickling sheet is that it can effectively reduce the purchase cost under the premise of ensuring the surface quality and use requirements. At present, many enterprises put forward higher and higher requirements for high performance and low cost of steel. With the continuous progress of steel rolling technology, the performance of hot rolled sheet is approaching to that of cold rolled sheet, so that "replacing cold with hot" can be realized technically. It can be said that pickling plate is between cold rolled plate and hot rolled plate performance ratio is relatively high a product, has a good market development prospects. But AT present, THE use of acid WASH plate in various industries in our country has just started. The professional production of acid wash plate has started to go into production from September 2001 at BaoSTEEL Acid Wash production line.
