Pickling is a very important process in the production process of cold-rolled strip steel. Its purpose is to remove the iron oxide on the surface of the strip steel and cut off the crack edges to provide qualified blanks for the rolling mill to ensure that the cold-rolling mill can produce qualified strips smoothly. Steel products.
The pickled plate is made of high-quality hot-rolled sheet as the raw material. After the oxide layer is removed by the pickling unit, after trimming and finishing, the surface quality and use requirements (mainly cold bending forming or stamping performance) are between hot-rolled plate and cold-rolled The intermediate product between the plates is an ideal substitute for some hot-rolled and cold-rolled plates.
