The Reforming of Short Net System of No.1 Electric Arc Furnace

文章介绍了莱钢机械厂铸钢车间１＃电弧炉短网系统的改造过程。通过改造，提高了导电横臂的机械强度，降低了系统的阻抗，吨钢电耗降低了１７．２ｋＷ·ｈ，年直接经济效益达７９．７１万元。

This paper introduces the reforming process in cast steel section of the machinery plant of Laiwu iron and steel general works.Because increasing the machinery strength of conducting arm and decreasing the impedance of this system the power consumption of every ton of steel is decreased by 17.2kWh and the direct profit is up to 0.7971 million yuan (RMB)/a.
