ABSTRACT:
A metallurgical plasma melting furnace for the melting of metals and alloys is provided with a substantially cylindrical melting vessel and a plurality of plasma burners disposed in burner openings in the walls of the vessel for creating flow stable plasma arcs. The vessel includes a first vertical cylindrical domain and a second vertical cylindrical domain divided by a vertical longitudinal plane and wherein the burners are located in the first cylindrical domain facing the second cylindrical domain and positioned such that the points of intersection of the projections of the burner axes are disposed in the second cylindrical domain and the distance between the intersection points is less than the radius of the vessel.
