METHOD AND APPARATUS FOR PRODUCTION OF CAST IRON FROM IRON COMPOUNDS

摘要

FIELD: ferrous metallurgy. SUBSTANCE: iron compound is preliminarily reduced in the first chamber with symmetrical (on rotation) wall and then further reduced in the second chamber disposed under first one using fuel and oxygen supplied into second chamber. Reducing gas passes upward into the first chamber for preliminary reduction. Iron compounds in the first chamber are melted at least partially and flow down over the wall in direction of second chamber. Iron compounds are introduced into first chamber in particulate state by agency of gas carrier in the form of one or a few jets having tangential constituent. Oxygen introduction rate is higher than that of iron compounds in oxygen jets. The latter rate is such as to provide iron particles' reaching first chamber wall in at least partially molten state. EFFECT: enhanced efficiency of process.
