What is the process flow of stainless steel hot rolling?

I believe many friends outside the industry don't know very well. Next, I'll bring you a description of the stainless steel hot rolling process,

The hot rolling process of stainless steel takes slab (mainly continuous casting slab) as raw material, which is heated and then made into strip steel by roughing mill and finishing mill. The hot steel strip from the last finishing mill is cooled to the set temperature through laminar flow, and then rolled into steel coil by coiler. After cooling, the steel coil has oxide skin on the surface, showing black, commonly known as "stainless steel black skin coil". After annealing and pickling, the oxidized surface is removed, which is the "stainless steel white coil". Most of the hot-rolled products in the stainless steel market are stainless steel white coils.
