METALLURGISCHER PLASMASCHMELZOFEN

摘要

1. Process for melting metals and alloys by means of a plasma-melting furnace where, independent from the nature of the charging material (6), the plasma burners (3) operate with fullpower shortly after the melting started, characterized in that a crater is molten in the charging material adjacent the plasma burners (3), by at least one auxiliary burner for starting being arranged in an acute angle to the axis of the adjacent plasma burner (3) in the same aperture of the furnace wall, operating immediately with full power and being fed with liquid or gaseous fuel, and that after gaining a fusing sufficient for plasma torch the plasma burner (3) is ignited and the auxiliary burner (4) for starting is switched off.
