СПОСОБ ЭЛЕКТРОПЛАВКИ В ДУГОВОЙ ПЕЧИ ПОСТОЯННОГО ТОКА

摘要

FIELD: electric metallurgy. ^ SUBSTANCE: method comprises control of parameters of arc and power source by imposing pulsations to the total arc current and supplying pulsating flux of plasma-generating gas to the interelectrode space through the axial opening in the arch electrode. The frequencies of the pulsations of the arc current and the flux of plasma-generating gas range from 0.1 Hz to 10 Hz. ^ EFFECT: enhanced quality of melting. ^ 1 cl, 2 dwg, 1 tbl
