    摘要： 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 pump effect for the next treatment or technological actions such as the continuous or periodical casting through a filter for the mechanical filtration of the agglomerates.

    摘要： A melting furnace for insulating materials is provided with a cooled crucible (10) having continuous metal side malls, a partitioned and cooled bottom (12) and at least one induction coil (28) placed under the bottom which serves as the sole heating means. The depth of the melting bath contained in the crucible and the excitation frequency of the induction coil are selected so that the depth and half of the inside radius of the crucible are less than the skin thickness of the bath.
