Melting crucible induction furnace with a protective device against the escape of low-melting metals, by the crucible wall

摘要

a schmelztiegelinduktionsofen with protection against metals with low melting point is in a trommelbehu00e4lter induction coil arranged in a refractory crucible.the schmelztiegelinduktionsofen is such that it has a spulenschutzelement, between the refractory crucible and induction coil is inserted and at least one gasdurchlu00e4ssigen area. with the gasdurchlu00e4ssigen area is a gaszufu00fchrungsrohr in conjunction to the refractory crucible with beaufschlagtes gas such as air under pressure.the gasdurchlu00e4ssige area is arranged in such a way that the pressure is distributed beaufschlagte gas so that the pressure between the upper part of the refractory crucible and its prevent defects mainly in relation to the decreasing distance to prevent defects increases.
