摘要
Abstract
The exhaust manifold casting has many isolated hot-spots and it is impossible to set risers on it. To solve this problem, the Huazhu CAE software is applied to predict the position of shrinkage and dispersed shrinkage, and the proportional solidification technology is used to design the gating and feeding system. The riser neck must be 'wide, thin, short and declining', which is the key technology to take full advantage of self-feeding by graphite self-expansion. After optimization of process parameters, the shrinkage defects of manifold were effectively eliminated, thereby the process yield was increased significantly and a significant economic benefit was obtained.关键词
