摘要
电渣重熔钢锭中的氧主要来源于自耗电极中的原始氧、在电极制造和重熔时渣池上方电极表面生成的氧化铁皮、渣料带入的不稳定氧化物和电渣重熔过程中气氛中的氧,为了有效地控制电渣锭中的氧含量,必须使用复合脱氧剂对自耗电极进行终脱氧,对自耗电极表面进行处理,严格控制渣中不稳定氧化物的含量,以及降低电渣重熔过程中气氛中的氧分压.
The primary sources of the oxygen content in ESR ingots are the oxygen in the electrodes, the iron scale on the consumable electrode surface, the nonsteady oxides in the fluxes, and the oxygen in the mold atmosphere during remelting. The reduction of the oxygen content of ESR metal can be achieved mainly by using compound deoxidizer as the final deoxidizer, descaling the consumable electrode surface, controlling strictly the content of nonsteady oxides in the fluxes and reducing the oxygen partial pressure in the mold atmosphere.
