MOLTEN IRON MANUFACTURING APPARATUS AND MOLTEN IRON MANUFACTURING METHOD

摘要

Provided is a molten iron manufacturing method manufacturing molten iron by rapidly heating coal after charging the coal in a dome part of a melting and gasifying furnace of a molten iron manufacturing apparatus, so as to form char in a large size by reducing the degradation of coal briquettes charged in the melting and gasifying furnace, the molten iron manufacturing apparatus comprising: the melting and gasifying furnace charging reduced iron; and a reducing furnace connected to the melting and gasifying furnace, and providing the reduced iron, and the method comprising the steps of: i) carbonizing the coal and providing the carbonized coal; ii) providing the reduced iron obtained by reducing iron ore in the reducing furnace; and iii) providing the molten iron by charging the carbonized coal and the reduced iron in the melting and gasifying furnace.
