For cold rolling, we use many kinds of high alloy tool steels, and heavy powder unmetallurgical steels are the basic materials for cross cutting knives.
The cutting tool can be used for cutting: all kinds of cold rolled sheet, crushing, forming, cutting, flying shear, etc. Disc scissors are mainly used in various cold rolling mills and hot strip mills to improve the width accuracy of strip. The upper and lower pieces overlap, and the left and right groups are sheared. The parallelism of the blades is controlled within +0.05. It is mainly made of Cr12MoV, H13, H13Ni, LD and other high-quality alloy steels. It meets the customers' needs in the process of using, such as small shear burr, flat cutting edge of sheet metal, non-breaking blade and so on.
