Cleaning plate is an intermediate product with high quality hot rolled sheet as raw material, after removing oxide layer by pickling line, trimming and finishing, surface quality and use requirements (mainly cold bending forming or stamping performance) are between hot rolled plate and cold rolled plate. It is an ideal substitute for some hot rolled plate and cold rolled plate.
Compared with hot-rolled plate, the advantages of pickling plate are as follows: 1) good surface quality, because the hot-rolled pickling plate removes the surface scale, improves the surface quality of steel, and is convenient for welding, oiling and painting. 2) High dimensional accuracy, after leveling, the shape of the plate can be changed to a certain extent, so as to reduce the deviation of 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 sheet, the advantage of cleaning sheet is that it can effectively reduce the purchase cost on the premise of ensuring the 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 rolling technology, the performance of hot rolled sheet is approaching to that of cold rolled sheet, which makes "heat instead of cold" realized in technology. It can be said that cleaning plate is a product with high performance price ratio between cold-rolled plate and hot-rolled plate, which has a good market development prospect.
