ABSTRACT:
In a method of producing homogenous ingots of high-melting, nitrogen-containing alloys, whose nitrogen contents are above the solubility limit at atmospheric pressure, according to the electric slag remelting process and using a pressure above atmospheric, a composite electrode consisting of at least one core made of a nitrogen-containing alloy and a jacket made of a nitrogen-containing alloy is used, wherein one of the nitrogen contents is higher and the other one is lower than that of the ingot to be produced.
