What's the difference between stainless steel strip 304 hot rolling and cold rolling?
Rolling at room temperature is generally understood as cold rolling, from a metallurgical point of view, below the rolling temperature at which the roll is rolled.Hot rolling is made of slab (mainly continuous casting billet), which is made up of roughing mill and finishing mill after heating
The cold rolled plate is mainly made of thin plate and rolled by plate at room temperature. Usually, subsequent surfaces are subjected to pickling, polishing, and passivation. The price at the factory level, of course, is expensive for cold rolling
The production process is different. The hot rolled plate is usually medium thick plate. The slab is heated to be rolled to thickness and then pickled.
