What is pickling?
The main processes of hot rolling pickling include laser welding, stretch straightening, turbulent pickling, in-line flattening, and trimming. Pickling specifications are generally 1.0 - 6.0 * 800 - 1650mm. Products include low, medium and high strength stamping steel, automotive structural steel , etc., mainly delivered in the form of steel coils. Process characteristics A beautiful, smooth surface is obtained by removing the scale from the hot rolled steel sheet. Features Reducing costs and replacing the cold-rolled sheets with pickled sheets can save costs for the company. The surface quality is good. Compared with the ordinary hot-rolled sheet, the hot-rolled pickling plate removes the surface iron oxide scale, improves the surface quality of the steel, and is convenient for welding, oiling and painting. The dimensional accuracy is high, and after flattening, the plate shape can be changed to reduce the deviation of the unevenness. Improves surfa...
