After rolling, there will be stress inside the stainless steel strips, which will cause problems such as curling of the stainless steel strips. In order to ensure the production quality of stainless steel strips, stress elimination is required. Existing stainless steel strip stress relief devices, such as a stainless steel stress relief device with publication number CN209792304U, can adjust the distance between the burner head and the stainless steel strip by turning the handle, and can flatten the arc-shaped curled stainless steel strip, so that the stress of the stainless steel strip can be effectively removed and the stainless steel strip can be flattened, thereby improving the quality of precision parts and components and being easy to use; When the above-mentioned existing stainless steel strip stress relief device is actually used, the stainless steel strip is cooled mainly by air cooling through a fixed heat dissipation fan, and the cooling range is small, resulting in poor cooling effect.
