It takes slab (mainly continuous casting billet) as raw material, and after heating, it is made into strip steel by rough rolling unit and finishing rolling unit. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and is coiled into a steel strip coil by the coiler.

The difference between hot rolling and cold rolling of stainless steel is that cold rolling is rolled on the basis of hot rolling.
