Rolling with the requirements of packaging steel strip

by:Hongmei     2020-04-05
Packaging steel strip roll forming process, it is a complex deformation process, the influence of many factors, the initial state of raw materials is also an important factor. First of all, when raw material is soft or hard points, it will be difficult to steady roll process, and even make the machine damage; Secondly, raw materials, though there is no soft or hard points, but if the material is too soft or hard, may also have on leaf size and requirements of deviation is large. The chemical composition of the band are shown in table 8 丨; Hardness is shown in table 8 - 2, tensile strength & sigma; b = 280 - $370 mpa, the surface light, no spots, no burr trimming edge requirement, also asked that the material evenly, no local soft or hard points.
