摘要
Abstract
The mathematical model of the mold thickness and casting is established, which is for the A356 aluminum casting by permanent mold, the solidification state of casting is analyzed in multiple of mold thicknesses by simulation software. The results show that the time of the casting from the initial temperature of 700℃ to the liquidus temperature of 613℃ is very short, and it's a definite value, and it does not relate to the wall thickness; the time of the casting is decreased from the liquidus temperature of 613 ℃ to the solidus temperature of 557℃ with the increase of mold thickness, and it's getting closer and closer to a definite value, and it relate to the wall thickness and the initial temperature of the mold;there is an economical wall thickness in the permanent mold, when the wall thickness is exceeded, the solidification state will not change again.关键词
