在自行研制的半固态镁合金流变铸轧设备上进行了半固态镁合金流变铸轧试验。采用斜坡冷却法制备了AZ91D镁合金半固态浆料，研究了浇注温度、浇注温度、静置时间、斜坡角度和斜坡长度等工艺参数对半固态浆料组织的影响。结果表明，工艺参数对半固态镁浆料的组织有很大影响。结果表明，斜坡法的最佳工艺参数为：浇注温度630 ℃，坡角60°，坡长0.570m。
The experiment of the rheocasting-rolling for semi-solid magnesium was carried out on the equipment made by ourselves in our laboratory. Semi-solid AZ91D magnesium slurry was prepared by cooling slope and the evolution of microstructure under different technological parameters such as pouring temperature, casting temperature, standing time, angle of slope and length of slope et al were studied. The results show that the technological parameters have great influence on the microstructure of the semi-solid magnesium slurry. The results show that the optimum parameters of slope method were: pouring temperature 630 degrees；angle of slope 60°；length of slope 0.570m.
