Abstract: With using the process measures including increasing the return ratio and miniaturizing the burden, con¬trolling the start-blowing oxygen temperature, heating rate and end-point temperature, modifying the high melting point and low basicity slag series to high basicity of CaO/ SiO₂ 1.4 ~2.5 and low melting point 45.6 ~ 53.6 CaO-21.6 ~ 32.0 SiO₂- 3 ~ 13 Cr₂O₃-5 - 10 MgO-5 ~ 10 Al₂O₃-0 ~5 CaF₂ slag series, and reasonable power supply system the tap to tap time of stainless steel is shortened by 30 minutes per heat, the power consumption is reduced by 75 kWh/t, the electrode consumption is reduced by 1. 89 kg/t, the furnace life is increased by 64 heats, and the content of Cr₂O₃ in slag is reduced to 6% 〜 12%

摘要： 通过提高返回比并使炉料小型化,控制冶炼过程开始吹氧温度、升温速度和终点温度,将高熔点、低碱度渣系优化为CaO/SiO21.4～2.5的高碱度、低熔点的45.6～53.6 CaO-21.6～32.0 SiO₂-3～13 Cr₂O₃-5～10MgO-5～10 Al₂O₃-0～5 CaF₂复合渣系,以及采取合理的供电制度等工艺措施,使不锈钢冶炼时间缩短30 min/炉,电耗降低75 kWh/t,电极消耗降低1.89 kg/t,炉龄提高64次,渣中Cr₂O₃含量降低到6%～12%。
