摘　　要：为提高电弧炉炉衬寿命，降低耐火砖消耗，石横特殊钢厂采取了提高渣中ＣａＯ浓度，降低（ＳｉＯ２）与ＭｇＯ的结合；提高渣中ＭｇＯ含量；控制吹氧操作等措施，使２０ｔＨＧＸ型电炉的炉体寿命由６７．７炉提高到８０．５炉，耐火砖消耗降低１．９６ｋｇ／ｔ钢。For increasing the service life of electric arc furnace lining and decreasing the consumption of refractory brick,some measures consisted of enhancing CaO thickness in slag,lowering combined SiO 2 with MgO,enhancing MgO content in slag,controlling oxygen blast process,etc,are taken on Thus the service life of 20t HGX electric arc furnace body is increased from 67 7 heats to 80 5 heats and the consumption of refractory brick is decreased by 1 96kg/t steel
