Manufacturing process

Cold rolled strip

1. Using “stainless steel strip/coil” as raw material, it is rolled into a material by cold rolling machine at normal temperature. Conventional thickness <0.1mm～3mm>, width <100mm～2000mm>;

2. Cold rolled steel strip/coil has the advantages of smooth surface, smooth, high dimensional accuracy and good mechanical properties. Most of the products are in coils and can be processed into coated steel plates;

3. Cold-rolled stainless steel strip/coil production process: pickling → normal temperature rolling → process lubrication → annealing → flattening → precision cutting → packaging → to reach the customer.

Hot rolled strip

• Strip steel with thickness of 1.80mm-6.00mm and width of 50mm-1200mm is made by hot rolling machine.

2. Hot rolled strip/sheet has the advantages of low hardness, easy processing and good ductility.

3. Production process of hot-rolled stainless steel strip/coil: pickling → high-temperature rolling → process lubrication → annealing →  flattening → precision cutting →  packaging → to reach the customer.

The difference between hot and cold

• Cold-rolled steel strip has good strength and yield ratio, and hot-rolled steel strip has good ductility and toughness.
• The surface quality, appearance and dimensional accuracy of cold-rolled steel strips are better than hot-rolled sheets.
• The thickness of cold-rolled steel strip is ultra-thin, and the thickness of hot-rolled steel is large.

Silicon steel thin strip

The grain-oriented silicon steel thin strip is also called cold-rolled silicon steel strip for telecommunications industry. It is used to manufacture various power transformers, pulse transformers, magnetic amplifiers, converters and other iron cores with operating frequencies above 400 Hz. Silicon steel thin strips larger than 0.20mm.
