摘要
通过优化炉料结构-采用铁水热装技术;集束氧枪技术强化供氧;疏通物流-强化二次精炼和增加连铸生产能力,使1台60t AC炉和1台60t DC炉的年生产率由改造前25.45万t增至87.34万t,冶炼周期由107 min/炉降至71 min/炉,电耗由547 kWh/t降至213 kWh/t,变压器利用系数由3142 t/(MVA·a)增至10783 t/(MVA·a)。探索出适合大冶特钢实际生产的冶炼工艺,取得了良好的经济技术效果。
With optimizing charging structure- using hot metal charging technology; intensifying oxygen supply by coherent oxygen lance technique; material flow sheet revamping by intensifying secondary relining and increasing concasting production capability, the annual steel output of a 60 t AC furnace and a 60 t DC furnace increased from before revamping 254 500 t to 873 400 t, tap-to-tap time decreased from 107 min to 71 min, electric power consumption decreased from 547 kWh/t to 213 kWh/t, coefficient of utilization of transformer increased from 3 142 t/（ MVA · a） to 10 783 t/（ MVA · a） to get a available steelmaking process at Daye Special Steel and obtain better economic and technology effect.
