The hot-melt process of electroconductive materials in an induction melting furnace and for this purpose with cold crucible furnace

摘要

P the invention has for its object a process of melting of an electrically conductive material (1) in a melting furnace (10) by induction in the cold crucible, in which it confines electromagnetically a mass of the electrically conductive material (1) to its melting temperature is decanted, the particles of inclusion contained in the electrically conductive material (1) the liquid by creating in the said material by the electromagnetic stirring, at least a vortex, a part of the mass of the electrically conductive material (1) the liquid in a casting tube (15) arranged at the - below the melting furnace (10), the jet of the electrically conductive material (1) the liquid to an electromagnetic confinement radial and it provides a vertical coaxial alignment of the electro - magnetic field acting on the mass of the electrically conductive material (1) and on the jet of the said mass. & br / the invention also relates to a melting furnace by induction in the cold crucible for the implementation of this process. / p
