The rolling is one of the common methods for producing the magnesium alloy plate, and the production process can refine the structure of the magnesium alloy plate, improve the mechanical property of the magnesium alloy plate and has the advantage of continuous batch production. However, the magnesium alloy plate is easy to have edge cracks during the rolling process, and the large amount of edge cutting waste generated by the edge cracking process seriously influences the yield and the material utilization rate of the magnesium alloy plate, so that the further development of the magnesium alloy plate is limited. The magnesium alloy plate has the characteristics that the edge crack factors are more, the uniformity of the blank structure, the rolling temperature, the width and the thickness of the blank and the like are all related to the edge crack, and most of the edge crack is generated as a result of the combined action of the factors. In particular, magnesium alloys have poor ductility, and in rolling, the edge portions of the rolled piece are subjected to additional tensile stress during elongation and the intermediate portions are subjected to additional compressive stress, so that the rolled piece becomes crowned. When the edge portion is subjected to a stress greater than its tensile strength, transverse cracks are generated and split from the outermost side edge, extending toward the center of the sheet.
