Abstract

It is a problem in solidification control and gas control for low pressure casting metal mold super-large aluminum alloy conductor （air tightness part）

compared to sand casting. Through setting rational pressure-applied parameters

adding processing supplement and setting rational chill

the conductor with compact structure can be produced. Meanwhile

gas hole in the conductor can be effectively eliminated by selecting rational filling parameters and enhancing exhaustion of metal mold as well as treating chill. The conductor passes examination after assembling.
