METHOD FOR PRODUCTION OF NORMAL ELECTROCORUNDUM Russian patent published in 2001 - IPC

Abstract RU 2171225 C1

FIELD: abrasives. SUBSTANCE: electrocorundum is prepared by smelting crude bauxite blend in presence of carbon reducing agent, for which dosed amounts of blend with moisture content are regularly loaded by portions each constituting 10-20% of the total weight of blend, the total is melted for 9-12.5 h, and finally electrocorundum and ferrous alloy are separately discharged. If necessary, smelt is chemically corrected by adding preliminarily dried bauxite (5-30% of its total amount) in the end of smelting. EFFECT: threefold reduced productive expenses and facilitated operation. 2 cl, 2 tbl
