Pickling plate is an intermediate product between hot-rolled plate and cold-rolled plate with high-quality hot-rolled plate as raw material, surface quality and application requirements (mainly cold bending forming or stamping performance) after removing oxide layer, trimming and finishing by pickling line. It is an ideal alternative product for some hot-rolled plates and cold-rolled plates.
Compared with hot-rolled plate, the advantages of pickling plate are mainly as follows:
1) The surface quality is good, because the hot-rolled pickling plate removes the surface oxide scale, improves the surface quality of steel, and is convenient for welding, oiling and painting.
2) The size accuracy is high. After leveling, the shape of the plate will change to a certain extent, so as to reduce the deviation of the unevenness.
3) The surface finish is improved and the appearance effect is enhanced.
4) It can reduce the environmental pollution caused by scattered pickling.
Compared with cold-rolled plate, the advantage of pickling plate is to reduce the purchasing cost effectively under the premise of ensuring the use requirements of surface quality. 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 "hot instead of cold" can be realized in technology.
It can be said that pickling plate is a kind of product with high performance price ratio between cold rolled plate and hot rolled plate, which has a good market development prospect.
