| 摘 要： | 铸钢减速机壳体加强筋根部易产生热裂纹，其原因是加强筋与薄壁处不能同时凝固。为此，利用板形外冷铁降低浇注温度，采用７０砂制芯及合理布置浇注系统，有效地解决了铸造裂纹问题。

| Abstract: | Because of strengthening rib is not to simultaneous coagulating with thin wall position of casting steel piece,the strengthening rib root of reducer case made from casting steel is easily to produce hot crack.Through taking decreasing pouring temperature used of external chill of plate type,taking 70 core and reasonable arrangement of pouring system the question of casting crack can be salved effectively. |

| Keywords: | hot crack sequence coagulating simultaneous coagulating coagulanting shrinkage |
