METHOD OF CARNALLITE PREPARATION FOR ELECTROLYTIC PRODUCTION OF MAGNESIUM AND CHLORINE

摘要

FIELD: metallurgy.SUBSTANCE: proposed device comprises vessel composed of lined case divided by divided by partitions into carnallite fusion chamber, melt chlorination chamber to be heated by graphitised electrodes and melt settling chamber, tuyeres to feed chlorine-containing gas and taps to discharge the melt. Melt chlorination chamber can be heated by four electrodes arranged in pairs and shifted towards sidewalls. Distance L between chlorination chamber wall and electrode pair makes 600-700 mm. Relationship between distance Lbetween axes of two electrodes and distance Lbetween axes of said two electrodes equals 1 : (2-3). Relationship between total area of electrodes Sand total area Sof chlorination chamber makes 1 : (25-50), while relationship between height h of electrode penetration into melt and electrode height H equal 1 : (3-6).EFFECT: higher purity of carnallite.3 dwg, 1 ex
