This paper analyzes the causes of a large cylinder body sidewall shrinkage.Too low temperature and the feeding failure of the hot spot.With the MAGMA simulation software,by increasing the pouring temperature,adjust the gating system,increasing the cold iron and other measures to solve the sidewall shrinkage.%分析了一种大型机体的侧壁缩松的形成原因,温度过低、热节处未能补缩.借助MAGMA模拟分析软件,通过提高浇注温度,调整浇注系统,增加冷铁等措施,解决侧壁缩松.
