Compound Degassing of A356 Aluminum Alloy

Cheng Shujian;Qiu Libao;Liu Feng;Zhang Xiaoguang;Tianjin Lizhong Group Co.,Ltd.;  
Influence of two kinds of swirling rotor on bubble in aluminum alloy was analyzed by water simulation.A compound degassing process was explored by using gas permeable brick,rotary degassing and compounded degassing process.The results show that the shape of the rotor has a great influence on the effect of degassing effects of aluminum liquid.The double rotor can crush the bubbles fully and disperse the bubbles even more,thus achieving the satisfied degassing effect.The degassing effect of spinning spray on the bottom aluminum fluid is poor,while the degassing efficiency of the permeable brick is low.The compound degassing with gas permeable brick and rotary degassing can treat the aluminum liquid in the bottom of container and improve the degassing efficiency markedly as well as increasing the density of aluminum liquid.
