介绍了一组使电弧炉各期均运行在最佳状态的计算机软件程序。它在不同的冶炼期 ,能自动地改变弧流和弧压的工作点 ,以及串联电抗器的抽头。在电极穿井期 ,电弧被炉料包围、热能辐射炉料 ,此时程序给出长弧作业。在主熔化期 ,运行电抗减小 ,多种能源利用 ,程序自动降低电炉变压 A set of computer software programs are presented that allow the arc furnaces to run at optimum conditions throughout the period. It is different in the smelting period, can automatically change the arc current and arc voltage of the operating point, and the series reactor taps. In the electrode wear period, the arc is surrounded by charge, thermal radiation charge, the program gives a long arc operation. In the main melting period, reducing the operating reactance, a variety of energy use, the program automatically reduce the electric transformer
