50t电炉铁水热装工艺节能降耗实践分析

THE SUMMARY AND ANALYSIS ON CHARGING MOLTEN IRON INTO 50t EAF

完成了铁水热装入 ５０ ｔ超高功率电弧炉的试验，节能效果显著，电耗降低 ３０－１０ ｋＷ·ｈ／ｔ，平均为 ５０ ｋＷ·ｈ／ｔ；冶炼时间缩短 ５—２０ ｍｉｎ平均 ７ ｍｉｎ．并对影响冶炼电耗、时间的关键问题进行了分析．

The test of adding liquid iron into 50 t ultrahight power electric arc furnace (EAF) has been successfully finished, and the results show that the projection, the consume power decreases 30-100 kW·h/t (averge 50 kW.h/t) and the smelting time 5-20 min (average 7 min). In this paper, the factors affecting the consume electricity and the smelting time are analysed.
