摘要

基于物理模拟

采用低熔点金属镓对薄壁件在行波磁场下的充型过程规律进行研究。结果发现

合金充型能力、充型流量和充型长度都随充型电流即磁感应强度的增加而增加

而充型时间则随充型电流的增加而减少。下型采用不导磁的不锈钢材料较陶瓷材料要好

充型电流为2 100At时效时最佳。

Abstract

Filling process of thin-walled casting in the traveling magnetic field was analyzed with the help of low melting point metal gallium physical simulation.The results reveal that filling ability

filling flow and filling length are increased

while the filling time is decreased with the increase of the magnetic induction intensity.The stainless steel bottom-mold was superior to ceramic bottom-mold

and the optimized process parameters were presented.
