FUSION INTRODUCTION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2009 - IPC H05B7/10 

FIELD: metallurgy.

SUBSTANCE: invention relates to electrothermics field. Management of heating and melting method is achieved by that in melt introduction, including location of electrode assemblies in melting tank, loading of feed material, feeding on electrodes of voltage, arc-through, installation of electrodes into working position, displacement of electrodes is implemented independently of molten material and melt location into any point of working space of melting tank, including bottom part; gas consumption, fed into cavity between external and internal electrode and into space between electrode assembly and melting tank case, it is regulated independently to each other in limits from 0 up to of nominal, herewith changing of gas consumption and reciprocal deflections of electrodes there are specified shape and direction of arc and plasma jet between electrodes and between electrode assembly and melting tank case. Device contains melting tank, one or more electrode assembly with one or more power supply of each electrode, in which each of units consists of two co-axial located electrodes, outfitted by self-contained electrode-drive assembly.

EFFECT: it can be used for manageable, including continuous, heating and melting as low-melt, as high-melting materials in a wide range - from metals up to nonmetallic materials, including oxides.
