摘要
在废钢含S≤0．083%、P≤0．190%条件下试验,实现了取消氧化期和还原期的操作,容量3吨电弧炉熔炼普碳钢,平均单炉冶炼时间为65．9分钟。经五年时间的生产验证,技术、经济指标令人满意。新工艺己应用于B3、25Mnsi、45、ZG45等钢种的生产。
A expeiiment has been carried out in this paper by employing steel scrap containing S<0.083%, P 0.190% and the average melting time of carbon steel melted in 3t electric arc furnace was reduced to 65.9 nun , to cancel successfully Oxidation period and reduction period. For five years production experiments have proved that all the lechno-economic targets are of satisfactory and this process has been used for production of steel B3, 25MnSi, 45 and ZG45 etc.
