高阻抗电弧炉的电弧功率特性

摘要

高阻抗电弧炉的电弧功率影响熔化速率,但是电弧功率不仅取决于电参数(电弧电流、电弧电压),而且在很大程度上取决于电弧区等离子气体的热特性.即电弧功率的数值还随着采用高热容量的等离子气体而加大.%The arc power of the high impedance EAF affects the melting rate. Power delivery in a high impedance EAF is influenced not only by the electric parameters such as arc current and arc voltage, but also by thermal properties of the gases that form the plasma gases in the arc region. Namely, arc power is enhanced with high heat capacity plasma gases
