The surface of the local cold steel plate is a small piece of overlapping thin layer that is not exfoliated and presents a mountain-like or line-like shape. The material has holes.
The material contains non-metallic inclusions. When cold rolling, the local tensile strength exceeds the limit, so that the material is partially broken to form holes;
Hot-rolled raw materials are produced with severe scratches, chisel marks and other defects, which are torn after cold rolling.
The edges of the local cold steel plate are cracked and penetrate deep into the inside of the steel strip in the width direction.
The thinner the local cold steel plate, the easier local cold steel plate is to form this defect. Traces after clipping due to edge cracking.
