The steel coil side drum is mainly due to the irregular shape of the transverse cross-section of the hot-rolled steel coil, that is, the local production of high points, resulting in the cold-rolled steel strip at the high point of the bulge or strip-shaped convex defects.
The steel coil side drum is mainly due to the irregular shape of the transverse cross-section of the hot-rolled steel coil, that is, the local production of high points, resulting in the cold-rolled steel strip at the high point of the bulge or strip-shaped convex defects.
The local high points of the hot-rolled steel coil are basically the same in the width direction. Due to the thicker cold-rolled substrate, they will not appear when hot-rolled coil is taken. However, due to the inheritability of the plate shape, the extension of the cold-rolled steel strip in the length direction is uneven, and the extension of the high points is greater than that of other widths, resulting in plate shape defects and drum edges.
