电炉单渣冶炼是基本上取消炉内还原过程,氧化渣下出钢,包内强制脱氧、合金化的一种快速炼钢法。试验表明,在电炉上采用单渣工艺冶炼碳素铸钢,工艺稳定,质量可靠,经济效果明显,且冶炼操作简化,炉前劳动条件有所改善。铜铸件的质量主要是通过钢的化学成分(表1)和钢液温度控制加以实现的。 Electric furnace single slag smelting is basically to cancel the reduction process in the furnace, the oxide slag under the steel, the package forced deoxidation, alloying of a rapid steelmaking method. The test shows that carbon steel cast by single slag process on the electric furnace is stable, the quality is reliable, the economic effect is obvious, and the smelting operation is simplified and the working conditions in the furnace are improved. The quality of the copper castings is mainly achieved by the chemical composition of the steel (Table 1) and the temperature control of the molten steel.
