Preparation method of austenitic stainless steel hard rough surface product

A preparation method of an austenitic stainless steel hard rough surface product comprises the following steps: annealing and pickling a stainless steel black skin hot coil; intermediate rolling; annealing and pickling the stainless steel cold coil; hard rough surface rolling is conducted, specifically, rolling is conducted in multiple passes, rough surface rolling is conducted on the front surface and the back surface of the strip steel through a roughening roller with a certain roughness range in the final pass, the rolling rate is 10-20%, and the thickness of the rolled stainless steel reaches the required specification thickness; hard rough surface degreasing is conducted, specifically, alkali liquor is adopted for degreasing, the concentration of the alkali liquor is 3-10%, and rolling oil attached to the surface is completely removed; and finished product production: pasting a protective film special for laser cutting on the steel coil. The process is reasonable and easy to operate, the prepared product
