压边浇注在球墨铸铁生产上的应用

Application of Teemi ng Pressed on the Edge in Ductile Iron Production

通过改进球墨铸铁齿轮传统工艺的浇注系统及冒口的设置,使其原来的大冒口、多冒口改造为压边浇注系统与一个小冒口的工艺,既满足零件的机械性能与工艺性能,又达到了降低成本且质量稳定的目的。

By improving traditional teeming system aud riser distribution of ductile iron gear,makes original big and multiple risers be teeming pressed on edge system and a small ris er,which not only satisfies with mechanical and processing performance but also reduces cost and gets the steady quality requir ement.
