孕育铸铁件的无冒口铸造工艺

A Non-riser Casting Technology for Inoculated Cast Iron

本文运用铸铁件“均衡凝固与有限补缩理论”,对孕育铸铁的收缩特性和具体铸件的补缩特点作了分析。提出该类合金无冒口铸造工艺设计的方法,为铸铁件铸造工艺方案的制定开辟了新路。

Based on the principle of proporational solification condensation and limited feeding, this paper has de- VeloPed a creative analysis on the shrinkage feature of the inoculated cast iron and the feeding characterist for the typical cast workpieces, a conclusion mentioned that casting can be made by the non-riser technology The paper has also conclut- ed a design process of the new technology developed a new way for the determination of casting technology deign wbich for the cast iron.
