Moreover, with the works of the Lorentz force, the evenly solidified structure can be obtained in the electromagnetic centrifugal cast. 而洛倫茲力可以抑制熔體的流動和波動，提高溶質離子在基體中的固溶度，另外，利用洛倫茲力還可以在電磁離心鑄造中獲得均勻的凝固組織。
The mechanism and progress of soft reduction technology was introduced, the effect of the reduction on central segregation and solidified structure was analysed. 摘要介紹了輕壓下技術的作用機理及工藝過程，分析了壓下量對鑄坯中心偏析及鑄坯凝固組織的影響。
