铸钢件冒口所消耗的钢水一般占铸件重的二分之一左右,如果能够将冒口完全取消,将给国家节约很大一笔资金,也简化了工艺过程,缩短了造型时间,提高了生产效率.我车间目前生产的高锰钢件都是用于破碎机械内部的防磨零件,这些零件因与矿石、煤焦 Cast steel riser consumption of molten steel generally accounts for about one-half of the heavy castings, if the riser can be completely canceled, will save a lot of money to the state, but also simplifies the process, shorten the modeling time and improve The production efficiency of the high-manganese steel parts I currently produce are used to crush the internal wear parts of machinery, these parts due to the ore, char
