by:Hongmei     2021-03-15
The rolling forming process of the packaging steel strip is a complex deformation process affected by many factors, and the initial state of the raw material is also an important factor. First, when the raw material has soft or hard points, the rolling process is difficult to carry out stably, and even damage the machine; secondly, although the raw material does not have soft or hard points, if the material is too hard or too soft, it may cause The size of the blades obtained differs greatly from the requirements. Chemical composition of steel strip for rolling
   see Table 8-丨; For hardness see Table 8-2, tensile strength σb u003d 280-370MPa, the surface must be bright and free of pound marks and other defects, the edges must be trimmed without burrs, and the material must be uniform and local Point or hard point.
