Cold Rolling and Hot Rolling of Stainless Steel Strip

Cold rolling:
① Using “stainless steel strip/coil” as the raw material, it is rolled into material through a cold rolling mill at room temperature. Conventional thickness<0.1mm~3mm>, width<100mm~2000mm>;
② Cold rolled steel strip/coil “has advantages such as smooth and flat surface, high dimensional accuracy, and good mechanical properties. Most products are rolled into coils and can be processed into coated steel plates;
③ Cold rolled stainless steel strip/coil production process: 1. Pickling → 2. Room temperature rolling → 3. Process lubrication → 4. Annealing → 5. Flattening → 6. Fine cutting → 7. Packaging → 8. Delivery to customers.
Hot rolling:
① Strip steel with a thickness of 1.80mm-6.00mm and a width of 50mm-1200mm is produced by hot rolling.
② Hot rolled strip/sheet steel has the advantages of low hardness, easy processing, and good ductility.
③ The production process of hot-rolled stainless steel strip/coil: 1. pickling → 2. high-temperature rolling → 3. process lubrication → 4. annealing → 5. leveling → 6. precision cutting → 7. packaging → 8. delivery to customers.
Cold and hot differences:
① Cold rolled steel strip has good strength and yield ratio, while hot rolled steel strip has good ductility and toughness.
② The thickness of cold rolled steel strip is ultra-thin, while the thickness of hot rolled steel strip is relatively large.
③ The surface quality, appearance, and dimensional accuracy of cold-rolled steel strips are superior to hot-rolled plates.
