METHOD AND FURNACE FOR MELTING STEEL SCRAP.

摘要

The invention relates to a method for smelting steel scrap in a furnace, a working gas being blown into the furnace via a flow channel (8) in order to supply melting energy and being guided through at least one electrodeless plasma torch (10), the plasma being produced by at least one inductive heating coil (18) that coaxially encloses the flow channel (8) and forms a heating zone (17). The invention also relates to a melting furnace (1) comprising at least one heating device (6) that extends through a wall of the furnace, for supplying melting energy. According to the invention, the heating device (6) comprises a tubular body (7) which encloses a flow channel (8). A longitudinal section of the tubular body (7) is configured as an electrodeless plasma torch (10), said torch having an inductive heating coil (18) that coaxially encloses the flow channel (8) and forms a heating zone (17).
