Consteel电炉与烟道竖炉炼钢技术的比较

Comparison of Steel-Making Technology between Consteel Electric Furnace and Flue Shaft Furnace

从原辅料消耗、动力消耗等方面对Consteel电炉与烟道竖炉炼钢技术进行了对比。结果表明:Consteel电炉的预热温度较低;Consteel电炉吨钢电耗、烟气中二噁英含量、烟尘量耐材消耗比烟道竖炉低,但电极损耗却比烟道竖炉高,综合考虑,Consteel电炉炼钢技术将成为一种发展趋势。

This paper compares Consteel electric furnace and flue shaft furnace scrap steel-making technology in terms of raw and auxiliary material consumption and power consumption.The results show that the preheating temperature of the Consteel electric furnace is lower;the electricity consumption per ton of Consteel electric furnace,the dioxin content in the flue gas,and the refractory material consumption of the flue gas are lower than that of the flue shaft furnace,but the electrode loss is higher than that of the flue shaft furnace.Considering comprehensively,Consteel electric furnace scrap preheating technology will become a development trend.
