小型铸造车间内铸造球墨铸铁,往往在熔炼镁合金的设备上及在铁水包内加入镁合金时,会遇到许多困难。列宁格勒工艺研究院根据熔化球墨铸铁的经验,结果在铸造与加入镁合金方面,使小型铸造车间得到简单而又便宜的操作方法。由实验证明小型铸造车间可不必用镁铜与镁铝的合金。熔炼时所加的铜,除了保障操作上的安全外,乃是无谓的消耗。而且用镁铜合金还要经过二次处理,使时间处长,操作复杂,铁水温度也就须
Casting ductile iron in small foundries often encounters many difficulties when it comes to smelting magnesium alloys and adding magnesium alloys to ladle. Based on the experience of melting ductile iron, the Leningrad Institute for Process Technology has resulted in simple and inexpensive operation of small foundries in casting and joining magnesium alloys. Experiments show that small-scale foundry may not need magnesium-magnesium alloy with magnesium alloy. Copper added during smelting, in addition to ensuring operational safety, is useless consumption. But also with the magnesium-copper alloy after secondary treatment, so that the length of time, the operation is complicated, the hot metal temperature also
