摘要: Process for melting down and degassing lumpy material by means of inductive heating and under subatmospheric pressure in a melting crucible. For the purpose of shortening the duration of the process, scavenging gas and/or reaction gas is introduced into the bottom region of the melting crucible during at least 50% of the duration of the process until the material is melted down completely.
