Abstract

The fireproof lining for induction furnaces, esp. for induction crucible furnaces, is made with a central, retractable plug. The life of this plug is considerably extended by placing between the plug (11) and the dry tamped material (7) of the lining a layer of enveloping material (13) such as asbestos sheet or cardboard whose thickness is up to one hundredth of the plug. The hollow plug is subsequently removed and the envelope is supported by granular material (21) within the envelope. The lining is heated, the envelope decays on heating and the granular material is readily removed.
