大型铸钢齿轮敷砂外冷铁工艺设计与应用

Technological Design and Application of Sand-lined Cold Iron on Large Cast Steel Gear

通过理论计算设计了大型铸钢齿轮用敷砂外冷铁工艺,以取代传统的冒口加补贴工艺。生产试用表明,新工艺操作方便,与传统工艺相比,产品一次成品率由50%提高到100%。

Sandlined cold iron process used on large cast steel gear is designed by theory calculation, instead of the traditional riser contract. Experiment and production result show that the new process operates conveniently and comparing with the traditional process, the primary production yield is increased from 50% to 100%.
