Pickling steel plate

　　The pickling plate is made of high-quality hot-rolled sheet as raw material. After the pickling unit removes the oxide layer, trims the edge, and finishes, the surface quality and use requirements (mainly cold-rolled forming or stamping performance) are between hot-rolled and cold-rolled. The intermediate product between plates is an ideal substitute for some hot-rolled and cold-rolled plates. Compared with hot-rolled sheets, the advantages of pickling sheets are mainly:

　　1. The surface quality is good. Because the hot-rolled pickled plate removes the surface oxide scale, the surface quality of the steel is improved, and it is convenient for welding, oiling and painting.

　　2. The dimensional accuracy is high. After leveling, the plate shape can be changed to a certain extent, thereby reducing the deviation of unevenness.

　　3. Improve the surface finish and enhance the appearance effect.

　　4. It can reduce the environmental pollution caused by users' scattered pickling. Compared with cold-rolled sheets, the advantage of pickling sheets is that they can effectively reduce purchase costs on the premise of ensuring the surface quality requirements. At present, many enterprises put forward higher and higher requirements for high performance and low cost of steel. With the continuous improvement of steel rolling technology, the performance of hot-rolled sheet is approaching that of cold-rolled sheet, so that "replacing cold with heat" can be realized technically. It can be said that the pickling plate is a product with a relatively high performance-price ratio between cold-rolled plate and hot-rolled plate, and has a good market development prospect.
