Hot rolling uses slabs (mainly continuous casting slabs) as raw materials, and after heating, strips are made by rough rolling mills and finishing mills. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and then rolled into a steel strip coil by the coiler. The cooled steel strip coil undergoes different finishing operations according to the different needs of users. Lines (leveling, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) are processed into steel sheets, flat coils and slit steel strip products. To put it simply, after a piece of billet is heated (that is, the red hot steel block that burns on TV), it is refined and rolled several times, then trimmed and corrected into a steel plate. This is called hot rolling.

 

Hot-rolled stainless steel strips are made from hot-rolled stainless steel strips after further hot rolling. Compared with cold rolled strip, it has higher dimensional accuracy, low surface roughness, good surface quality, smooth Clean and high strength. Therefore, a thinner hot-rolled strip can be used instead of a thicker cold-rolled strip for the same purpose to save the amount of steel, which is of great economic significance. Hot-rolled stainless steel strip can be divided into five types according to the structure characteristics: austenite type, austenite-ferrite type, ferrite type, martensitic type and precipitation hardening type, which can be selected when used.
