METHOD OF PRODUCTION OF METALLIZED PELLETS Russian patent published in 1994 - IPC

Abstract SU 1383785 A1

FIELD: metallurgy. SUBSTANCE: metallized pellets are produced from iron ore raw material by reduction of raw pellets by suspension containing calcium oxide. Aqueous chalky suspension is used for the purpose, its consumption makes up 0.5 to 1.0 of the valve of dynamic moisture absorption of pellets. To increase the temperature threshold of pellets fusion at metallizing by 10 C within a temperature range from 700 to 900 C, the suspension density is increased by 2 kg/m3, and within a temperature range from 900 to 1050 C - by 10 kg/m3. EFFECT: reduced cost and enhanced quality of pellets. 1 dwg, 1 tbl
