PROCEDURE FOR CONTROL AND STABILISATION OF INTER-ELECTRODE SPACE Russian patent published in 2011 - IPC C22B9/20 

Abstract RU 2425156 C2

FIELD: metallurgy.

SUBSTANCE: procedure consists in measurement of voltage on arc at moment of arc presence in central part of end surface of electrode and in influencing electric arc and melt with axial magnetic field. Also, position of consumable electrode relative to a melted ingot is controlled. Electric arc and melt are influenced with radial rotating magnetic field with switching frequency of 0.1-0.3 Hz and intensity 60-80 oersted. Radial rotating magnetic field is generated by means of at least six parallel metal rods connected to a control current source; also, the rods are arranged coaxial to axis of a crystalliser on its external surface.

EFFECT: increased output of acceptable product.
