Abstract

The electrical arc furnaces of a direct current (EAFDC) have a lot of relevant advantages in comparison with furnaces of alternating-current. Low level of usage of electrodes and energy, a flame resistance, stable combustion of an arc, minor deterioration of quality parameters of the electric power concern to such advantages. But the most important advantage of EAFDC as contrasted to furnaces of alternating current is lower flicker effect. Desirable value of voltage of direct current furnaces is supported irrespective of current intensity, which one is controlled by separate thyristors. The aim of the research is the mathematical modeling a voltage-current characteristic (VCC) of an arc of a power steel furnace of a direct current and introducing it into the SALOMON program complex.

动力钢炉直流电弧电压-电流特性数学建模及其在SALOMON程序中的引入

与交流电弧炉相比，直流电弧炉具有许多相关的优点。电极和能量的使用水平低，具有阻燃性，电弧燃烧稳定，质量参数劣化小等优点。但与交流电炉相比，电弧直流电炉最重要的优点是闪变效应小。直流电炉电压的理想值与电流强度无关，电流强度由单独的晶闸管控制。研究的目的是建立直流动力钢炉电弧电压-电流特性(VCC)的数学模型，并将其引入SALOMON程序复合体。
