模数法在铸钢件冒口设计中的应用

The application of modular design method in cast steel items riser

铸钢件需要冒口进行补缩 ,模数法设计冒口比较科学 ,即MW ≥M件 及ε(V冒 +V件) ≤VWη冒口就有足够的液体补缩铸件 ,实现铸件无缩松、缩孔等疵病 。

This article is written to explain how to improve the efficiency of riser feeding for cast steel items by modular design method,and the quality of cast steel items is approved when MwM 件 and ε(V 冒+V 件) V r·η ,on shrinkage hole and porosity if this method is used
