description A high-efficient rolling process for magnesium alloy sheet. The process is a rolling process for rolling billets. Parameters of the rolling process are: the rolling speed of each rolling pass is 10ˆ¼50 m/min, the rolling reduction of each rolling pass is controlled to be 40ˆ¼90%, and both the preheating temperature before rolling and the rolling temperature of each rolling pass are 250ˆ¼450 °C. A preparation method for magnesium alloy sheet. The method comprises the steps of: 1) preparing rolling billets; 2) high-efficient hot rolling: controlling the rolling speed of each rolling pass to be 10ˆ¼50 m/min, controlling the rolling reduction of each rolling pass to be 40ˆ¼90%, and controlling both the preheating temperature before rolling and the rolling temperature of the each rolling pass to be 250ˆ¼450°C; and 3) performing annealing. By means of the rolling process, mechanical performance of the sheet can be also effectively improved, and especially, the strength and ductility of the sheet can be greatly improved.
