Description

Technical Field

[0001] The invention belongs to the technical field of hot rolling of stainless steel, and in particular relates to a device and method for controlling the side profile of a hot-rolled stainless steel slab. Background Art

[0002] During the post-rolling cooling of hot-rolled strip production, the temperature drop rate at the edge of the strip is usually faster than that in the middle, so that the temperature within a certain range of the edge of the strip is lower than that in the middle. When the internal stress caused by the temperature difference reaches the yield stress of the material, plastic extension deformation occurs, and when it continues to cool to room temperature, the lower edge wave defect remains; therefore, it affects the size of the side profile of the stainless steel, and further affects the control of the stainless steel's external dimensions.

[0003] After searching, the prior art publication number CN114042761A is a control method for eliminating the laminar cooling wave shape of thin-gauge patterned plates. The rolling control process parameters are designed from four aspects: controlling air cooling, laminar water cooling, coiling temperature and pinch roller pressure. The specific technical scheme is as follows: the laminar cooling equipment is arranged as follows: 4 groups of coarse adjustment sections, namely MZ1, MZ2, MZ3, and MZ4, each with 8 headers and a cooling length of 4.8 meters; 6 groups of fine adjustment sections, and the processing process has the following disadvantages: the thin-gauge patterned plates are leveled by pinch rollers, and the cooling water remaining on the surface of the thin-gauge patterned plates will be pressed into the surface of the thin-gauge patterned plates during the leveling process, thereby forming watermarks on the surface of the thin-gauge patterned plates, thereby affecting the quality of the thin-gauge patterned plates.

[0004] After searching, the prior art publication number is CN118218422A, which is a method for uniformly cooling hot-rolled low-carbon strip transversely, comprising the following steps: S1, the low-carbon strip passes through a laminar cooling section to reduce the strip temperature to the first-stage cooling temperature, and at the same time, the temperature difference between the middle and edge of the strip is reduced to within 15°C; S2, the low-carbon strip passes through an aerosol cooling section to reduce the strip temperature to the second-stage cooling temperature, and at the same time, the temperature difference between the middle and edge of the strip is further reduced to within 10°C; S3, the low-carbon strip passes through a water replenishment cooling section, and cooling water is sprayed in a spraying form to reduce the strip temperature to a suitable coiling temperature, and then the strip is sent to a coiler for coiling; the processing process has the following disadvantages: by controlling the cooling temperature, the temperature difference between the middle and edge of the strip is further controlled to drive the edge wave defects; however, it can only weaken the strip edge wave defects, and cannot smooth the edge wave defects caused by the temperature difference that still exists in some strips during the cooling process, thereby affecting the quality of the strip. Summary of the invention
