Moreover, with the works of the Lorentz force, the evenly solidified structure can be obtained in the electromagnetic centrifugal cast. 而洛伦兹力可以抑制熔体的流动和波动，提高溶质离子在基体中的固溶度，另外，利用洛伦兹力还可以在电磁离心铸造中获得均匀的凝固组织。
The mechanism and progress of soft reduction technology was introduced, the effect of the reduction on central segregation and solidified structure was analysed. 摘要介绍了轻压下技术的作用机理及工艺过程，分析了压下量对铸坯中心偏析及铸坯凝固组织的影响。
