PROCESS FOR DIRECT PRODUCTION OF CAST IRON FROM FINE IRON ORE AND FINE COAL AND APPARATUS SUITABLE TO CARRY OUT SAID PROCESS

摘要

A process for direct production of cast iron from fine iron ore and fine coal in an apparatus comprising one reactor provided with two areas in open communication where the process is carried out - one top area (1) and one bottom area (2) - such process encompassing the following operations: introducing iron ore together and simultaneously with a gas containing or consisting of oxygen into the top area (1) of the reactor through its side walls; introducing coal, oxygen, fluxes and a carrier gas into the bottom area (2) of the reactor through its side walls and introducing a stirring gas from its bottom, said apparatus including: the top area (1), provided with means (5) for introducing said iron ore and said gas; a discharge conduit (4), linked to the top area (1); the bottom area (2), arranged beneath the top area (1) and in communication with the top area (1) through a connection zone (3), provided with means (6, 7) for introducing oxygen, coal, fluxes and a carrier gas and with means for introducing a stirring gas.
