摘　　要：电炉采用煤氧助熔技术,能改变电炉原局部供热为大面积多点供热,从而炉料由渐近熔化变为同步熔化。30t电炉取得以煤代电、缩短冶炼时间27min,降低工序能耗9％,年增产6174t,吨钢成本降低2.36元的好成绩。Since the introduction of melting acceleration technique by coal-oxygen injection in the electric are furnace operation the heat supply has changed from partial supply pattern into a new one on a large area and multi point basis, and as a result the syn- chronous melting of furnace charge has replaced the previous mode of gradually melting. In the 30T electric are furnace remarkabe results have been obtained in subsitution of electricity by coal, reduction of refining time by 27 min, a 9％ decrease of energy con- sumption, an increase in productivity by 6174 ton steel/year and a reduction of produ- ction cost of 2.36 yuan/ton steel
