于２７０～３７０℃对常规铸造和搅动铸造的Ｚｎ—２０％Ａｌ合金的挤压加工特性进行了试验对比．结果表明，采用搅动铸造制得的坯料进行挤压时，挤压抗力较低，挤压品质量完好；而常规铸造坯料的挤压抗力较高，且在低于共析温度时，挤压品内部产生开裂。因此，搅动铸造锭在后继的加工过程中有其优越性。
At 270 ~ 370 ℃ on the conventional casting and stirring cast Zn-20% Al alloy extrusion processing characteristics of a comparison test. The results show that the extrusion resistance is low and the quality of the extruded product is good when the billet obtained by the stirring casting is extruded, while the extrusion resistance of the conventional cast billet is relatively high. When the temperature is lower than the eutectoid temperature, the extruded product Internal cracking. Therefore, stirring casting ingot in the subsequent processing has its advantages.
