ST37 Carbon steel coil

Pickling plate is made of high-quality hot-rolled sheet as raw material. After the pickling unit removes the oxide layer, trims and finishes, the surface quality and use requirements (mainly cold-formed or stamping performance) are between hot-rolled and cold-rolled The intermediate product between the plates is an ideal substitute for some hot-rolled plates and cold-rolled plates. Compared with hot-rolled plates, the main advantages of pickled plates are: 1. Good surface quality. Because the hot-rolled pickled plates remove 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 environmental pollution caused by users' scattered pickling. Compared with cold-rolled sheets, the advantage of pickled sheets is that they can effectively reduce purchase costs while ensuring the surface quality requirements. Many companies have put forward higher and higher requirements for the high performance and low cost of steel. With the continuous advancement of steel rolling technology, the performance of hot-rolled sheet is approaching that of cold-rolled sheet, so that "replacement of cold with heat" is technically realized. It can be said that the pickled plate is a product with a relatively high performance-to-price ratio between the cold-rolled plate and the hot-rolled plate, and has a good market development prospect. However, the use of pickled plates in various industries in my country has just started. The production of professional pickled plates began in September 2001 when Baosteel's pickling production line was put into operation.
