The so-called Hot sell grade 310s 304 316 321 stainless steel pipe production is not simply "cold rolling". Before cold rolling, annealing, pickling, grinding, etc. are required, and after cold rolling, leveling, straightening, shearing, stacking, etc. are required, so in fact, it is the whole process from the hot-rolled coil to the production of cold-rolled finished products.
1. Stainless steel is a kind of high-alloy steel, which has greater resistance to rolling deformation. In order to carry out high-efficiency and high-precision rolling, a rolling mill with high rigidity should be used, and a multi-roll cold rolling mill is generally used;
2. Special welding process is also a feature of Hot sell grade 310s 304 316 321 stainless steel pipe production;
3. In the production process of Hot sell grade 310s 304 316 321 stainless steel pipe, the raw material (hot-rolled coil) should be annealed, the cold rolling process should be intermediate annealing, and the final product should be annealed, so annealing is an important link in production;
4. Hot sell grade 310s 304 316 321 stainless steel pipe is a high-grade steel product with very strict requirements on surface quality. Not only the metallurgical defects caused by the previous process are not allowed to remain, but also obvious caused by the cold rolling process is not allowed. defect;
5. The production of Hot sell grade 310s 304 316 321 stainless steel pipe is a multi-unit joint operation. Process balance and process management are very important. There must be a strong production scheduling system to ensure continuous high-quality production.
