METHOD FOR BLAST SMELTING OF ZINC-CONTAINING BURDEN Russian patent published in 2002 - IPC

Abstract RU 2186117 C2

FIELD: metallurgy. SUBSTANCE: method involves forming buffer layer of coke and broken slag; periodically lowering burden charge level. Buffer layer is formed from separate coke and broken slag layers having predetermined height and weight ratio. EFFECT: increased efficiency by increased extent of removal of zinc from furnace shaft and simplified process of preparing and charging of buffer layer into furnace. 3 tbl, 1 ex
