Cold-rolled stainless steel is generally produced in coils. It is stainless steel sheet when it is flattened. Small batches of individual steel grades are produced by single sheet stainless steel sheet. Single sheet rolling is also suitable for trial production of new models and large-sized thicker steel sheets.
The production process of cold-rolled stainless steel plate is not only the cold-rolling process, but also includes heat treatment, pickling and grinding, leveling, cross-cutting to steel plate or longitudinally-cutting steel strip, and classification, cleaning and packaging of hot-rolled steel strip.
Because of the characteristics of stainless steel materials and the special requirements for product quality, the stainless steel cold rolling production process has the following characteristics.
Characteristics of cold rolling production process of stainless steel strip
First of all, due to the large rolling deformation resistance of stainless steel materials, in order to improve efficiency and ensure high rolling accuracy, a rolling mill with high rigidity is used, usually a multi-roll cold rolling mill.
Multi-roll cold rolling mills usually use a single-machine reversible rolling method, and the head and tail parts wound on the coiler are not rolled during rolling, and will be cut off as scraps. In order to improve the yield, a section of lead strip should be welded at both ends of the stainless steel strip before rolling, and the lead strip part is not rolled; in addition, if the quality of the hot-rolled stainless steel coil is too small, in order to improve the rolling efficiency and yield, Small steel coils should be welded into large steel coils in advance; in continuous annealing and pickling units, because of continuous operation, the head and tail connection parts of the steel strip should also be welded. Therefore, welding is an indispensable link in the production process of stainless steel strips. The welding difficulty of stainless steel is much higher than that of ordinary steel, so a specific welding process is also a feature of cold-rolled stainless steel strip production.
Before cold-rolling the stainless steel strip, the hot-rolled coil needs to be annealed first, and intermediate annealing is required during the cold-rolling process, and the final product needs to be finished annealing, so annealing is also a key link in production. There are many kinds of stainless steel materials, and their properties are different. The purpose, method and requirements of heat treatment are not exactly the same, and the process system is relatively unique.
Cold-rolled stainless steel sheets and strips have very strict requirements on their surface quality, and neither metallurgical and processing defects caused by the previous process nor obvious defects caused by cold-rolling are left. Therefore, various related elimination and protection measures have been adopted in the cold rolling production process. In fact, the cold rolling production process is a meticulous process, and its advantages are much higher than the production of other steel grades.
In addition, the finishing of stainless steel strips also has special requirements. For example, the flattening process should not only optimize the shape of the plate, but also use rolls with extremely low roughness to produce common bright 2B stainless steel plates. If it is ferritic stainless steel, it is also necessary to The formability of stainless steel sheets is optimized by controlling the amount of flattening. Because the stainless steel material is relatively hard; and there are stricter requirements on the straightness, it must be straightened with a strong straightening machine, and different straightening methods must be adopted according to the different thickness of the product.
