将超声波导入杆安装在水平式双辊铸轧机的凝固前沿,进行超声波镁板带的铸轧试验.对超声波铸轧镁板带和普通铸轧镁板带进行金相对比观察表明:普通铸轧镁板带枝晶网胞比较发达,组织不均匀,晶粒平均尺寸(直径)在50～60μm之间;而在镁铸轧过程中施加超声波能够使镁板带组织更加均匀,晶粒细化,晶粒平均尺寸(直径)在20～30μm之间.对镁板带的力学性能测试证实,超声波处理使铸轧镁板带的抗拉强度、屈服强度和延伸率比普通铸轧镁板带的分别提高了22.85%,49.78%和123.06%.
The ultrasonic lead-in rod was installed on the solidification front of the horizontal twin-roll casting mill, and the cast strip test of ultrasonic magnesium strip was carried out.The comparison of the microstructure of ultrasonic cast magnesium strip and ordinary cast magnesium strip showed that the ordinary cast-rolling Magnesium plate with dendritic cells more developed, the organization is not uniform, the average grain size (diameter) between 50 ~ 60μm; while the magnesium casting process in the application of ultrasound can make magnesium plate with a more uniform microstructure, grain refinement , The average grain size (diameter) of 20 ~ 30μm between the mechanical properties of magnesium plate test confirmed that the ultrasonic treatment of cast magnesium plate with a tensile strength, yield strength and elongation than ordinary cast magnesium plate Respectively, increased by 22.85%, 49.78% and 123.06% respectively.
