Manufacturer introduction: The production process of cold-rolled 8K mirror grade 201 ss stainless steel coil is not just the "cold rolling" process in the name. Its production process is very complicated. In addition to the process before cold rolling, there are also The process after cold rolling, in which the process before cold rolling includes steps such as annealing, pickling, grinding, etc. After cold rolling, it also needs to go through such processes as leveling, straightening, shearing, stacking plates, etc. After the first process, the cold-rolled stainless steel strip can be completely produced.
The cold rolling process of 8K mirror grade 201 ss stainless steel coil is actually a whole production process from the start of hot rolling to the finished product of cold rolling. Today, Xiaobian will talk about the specific production process of cold rolling.
Due to the characteristics of stainless steel strip and the high quality requirements, the cold rolling production process needs to do:
1. Stainless steel itself is a high-alloy steel material. During rolling, its deformation resistance will be relatively large. Therefore, in order to achieve high-precision and high-efficiency rolling, a high-rigidity rolling mill should be selected. Generally, manufacturers use multi-roller rolls. cold rolling mill.
2. When the stainless steel is cold rolled on the reversing rolling mill, the top part and the tail part wound on the coiler will not be pressed down, so it can greatly save materials and reduce waste.
3. In the production process, the raw materials need to be annealed. The intermediate annealing treatment needs to be carried out during the cold rolling process, and annealing is also required at the end of the process. It can be said that annealing is a very important process in the production process.
Cold-rolled 8K mirror grade 201 ss stainless steel coil is a relatively high-grade material. It has very high requirements on the quality of the product surface, and it is not allowed to have obvious defects in the cold-rolling process engineering.
