FIELD: process engineering. ^ SUBSTANCE: invention relates to metallurgy. Proposed plat comprises working chamber isolated from ambient medium to accommodate mix material loading device, independent heaters, stationary crucible with drain nose divided into melting and refining zones, and crystalliser. Heater represents electric-arc generator of low-temperature thermal plasma that generates pulsating arc flame with oscillation frequency of 0.1 to 10 Hz. ^ EFFECT: higher quality of blanks, ruling out of nonmetal inclusions. ^ 4 cl, 1 ex, 1 dwg |
