FORMATION TECHNIQUE OF FOAMY SLAG OVER MELT WHITH HIGH CHROME IN ELECTRIC FURNACE Russian patent published in 2009 - IPC C21C5/52

Abstract RU 2343208 C2

FIELD: metallurgy.

SUBSTANCE: mixture of metal oxide and carbon is introduced into furnace, at that metal oxide in sludge is reduced by carbon, and appeared gases form in sludge blebs, which make sludge foam. Mixture of metal oxide and carbon is introduced into furnace in the form of pressed and/or molded with addition of binding agent, particles, specifically, pellet.

EFFECT: regulation of gas generation process, leading to uniform sludge sponging.

11 cl, 2 dwg
