We analyzes the appearance and causes of folding and printing defects in stainless steel cold-rolled strip, and puts forward corresponding solutions on this basis. It has a practical guiding effect on improving the yield of stainless steel cold-rolled strip and expanding the application field.
Stainless Steel Strip Introduction
Stainless steel cold-rolled strip coiling and printing is a kind of strip steel that is partially rolled along the length of the reel body when the strip is coiled. During the strip coiling process, the lateral bulge of the steel strip occurs periodically at this part. Generally, periodic folding and printing defects with a certain length are formed at the strip coiling head, sometimes as long as hundreds of meters. These folds and marks formed on the surface of the strip are difficult to eliminate even after being flattened and straightened, which directly affects the application of products in high-end fields such as frosted boards, hairline boards and decorative boards.
