A process for melting an electroconductive material (1) in a melting furnace (10) by induction in a cold crucible includes electromagnetically confining a mass of the electroconductive material (1) up to its melting temperature. Then, at least one vortex is created in the liquid material to inclusion particles contained in the liquid electroconductive material. The vortex or vortices are created by electromagnetic stirring. A part of the mass of the liquid electroconductive material (1) is poured in a pouring tube (15) disposed under the melting furnace (10), subjecting the jet of the pouring of the liquid electroconductive material (1) to a radial electromagnetic confinement, and ensuring a vertical coaxial alignment of the electromagnetic fields acting on the mass of liquid electroconductive material (1) and on the pouring jet of the mass. An induction melting furnace employing a cold crucible for carrying out this is also disclosed.
