A VACUUM-PLASMA MECHANISM FOR THE TREATMENT OF METALLIC MELTS IN BATH

摘要

The invention relates to metallurgy, in particular to the structure of vacuum-plasma mechanism for the treatment of metallic melts in bath. The vacuum-plasma mechanism for the treatment of metallic melts includes plasmatron submerged into the liquid metal, vacuum chamber with dosing device for reagents disposed on the plasmatron, the lower face of which is placed at the distance of 50-250 mm higher than plasmatron nozzle, and outside diameter of chamber equals to 0.70-0.85 of the internal diameter of bath with melt. The invention provides an increase of processes of affinage and modification of melts in stationary conditions and in the flow, increasing efficiency of the plasma heating metal melt.
