Abstract: The present apparatus is comprised by two magnetic induction sets, one for melting of the raw material and the second for purification of molten metal; each set comprises a pot or crucible (1, 1'), an electromagnetic device, a filter (11) and a power supply; each crucible (1, 1') is surrounded in the lower part by a hollow permanent magnet (3, 3') in which three pairs of electromagnets facing each other are arranged; the process consists of the following stages: a) charging of metallic raw material inside a crucible (1); b) electromagnetic induction heating to melt the metallic raw material (2) inside crucible (1) through a three-phase magnetic system creating a horizontal travelling or pules magnetic field which builds a turbulent flux inside the melt (2'); c) whirling stirring of melt (2') by electromagnetic induction and purification of it via extraction of hydrogen and of non-electroconductive inclusions by coagulation of them in agglomerates; d) discharging of purified melt (2') by a magneto-hydrodynamic
