查询词典 die casting

The effects of casting temperature, casting speed and intensity of cooling water on microstructure are investigated. The results show that when the casting temperature, casting speed and intensity of cooling water are 710 ℃, 100 mm/min, 0.05 m 3/min respectively, the micros...

结果表明，铸造温度为710℃，铸造速度为100mm/min，冷却水强度为0.05m3/min时的低频半连续铸锭组织均匀细小，呈现近球形，边部和中间部位的晶粒大小差别较小，其平均晶粒尺寸分别为28μm和29μm。

The results show that with the increase of strain rate, the grain sizes of thermal simulation AZ31B alloys with different deformation all decrease; however, when other conditions are the same, the higher deformation will lead to the formation of the smaller grain size, and as the cooling intensity decreases, typical cast structure of AZ31B will appear. With the decrease of roll casting temperature, the dendritic size of roll casting AZ31B alloy sheet prepared by the same strain rate is also reduced, but with the increase of strain rate, the dendritic size of the alloy sheet prepared by the same initial roll casting temperature is decreased, and the tendency of dendritic streamline is strengthened. During the roll casting process of AZ31B alloy, rolling force should not be large, otherwise it will cause heat cracking.

研究结果表明：在不同应变量下，热模拟样品的晶粒粒度均随应变速率的增加而减小，而当其他条件相同时，变形量越大晶粒粒度越小，冷却强度降低，合金呈典型铸态组织；利用铸轧技术生产的AZ31B合金，当应变速率一定时，随着初始铸轧温度的降低，铸轧态板材的树枝晶粒度逐渐减小；而在初始铸轧温度一定时，随着应变速率的增大，铸轧态合金板材的树枝晶粒度也逐渐减小；而随着应变速率的提高，树枝晶沿轧向呈流线状排列的趋势增强；在AZ31B合金铸轧过程中，轧制力不能太大，否则容易引起热裂。
