A METHOD OF PRODUCTION OF LIQUID CARBONACEOUS METAL BASED ON IRON Russian patent published in 2003 - IPC

Abstract RU 2219245 C2

FIELD: metallurgy industry. SUBSTANCE: The invention presents a method of production of a liquid carbonaceous metal based on iron without application of an agglomeration of ores and coal carbonization. The method includes manufacture of pellets or cakes made of the fine-grained components of ore and coal materials, their feeding in the closed induction type electric crucible afterburning of the evolved gas by oxygen or air in the volume above the bath, transfer of the afterburning heat into the reaction zone by its emission by the furnace roof and liquid melt. The components for manufacture of the ore-coal materials and the metal additives are dosed counting upon production of the metal containing of no more than 3 % of carbon. Size of the ore and coal granules does not exceed 2.5 cm. EFFECT: the invention allows to intensify the process multiply higher, than one reached in industrial practice. 1 dwg
