大型铸钢件的铸造工艺往往设计有两个注浇系统。一个是通过总浇口从铸件本体部位进入型腔的浇注系统,另一个是通过另一只总浇口从冒口部位进入明冒口的浇注系统。为了保证铸件质量,浇注工艺要求钢液浇到超过铸件本体以上一定高度时(一般高出本体15至20厘米)中断浇注,将钢包移至另一浇注系统继续浇注,直至浇满冒口(俗称冲冒口)。如果在冲冒口前的浇注过程中稍不留意,让钢水浇得过高(进入冲冒口的内浇口中),那么,
Large castings casting process often design two injection system. One is through the main gate from the casting body into the cavity of the casting system, the other is through the other gate from the riser into the riser of the pouring system. In order to ensure the quality of the castings, the casting process requires that the molten steel be poured over a certain height above the body of the casting (typically 15 to 20 centimeters above the body) to stop pouring and move the ladle to another casting system to continue pouring until it is full of riser Risers mouth). If in the run-up before pouring in the process of paying little attention to the molten steel is too high (into the riser gate), then,
