COMBINER IRONMAKING FACILITIES

摘要

The present invention provides a complex iron manufacturing apparatus. According to the present invention, an iron manufacturing apparatus based on a flow reducing furnace and a coal-fillable melting gas brazier partially extracts and removes a CO_2 component contained in a final byproduct gas of the iron manufacturing apparatus; increases a temperature of the CO_2 component to manufacture high temperature reducing gas; and then supplies the high temperature reducing gas to a multi-stage flow reducing furnace which is separately arranged to reduce and plasticize fine ore and a subsidiary raw material to a prescribed level in the multi-stage flow reducing furnace to manufacture fine reduced bodies to supply the fine reduced bodies to an iron manufacturing apparatus based on a melting bath-type melting reducing furnace to stably operate the melting bath-type melting reducing furnace. The iron manufacturing apparatus based on the flow reducing furnace and the coal-fillable melting gas brazier uses high quality gas and raw materials to stably produce iron. The iron manufacturing apparatus based on the melting bath-type melting reducing furnace and connected to the iron manufacturing apparatus based on the flow reducing furnace and the coal-fillable melting gas brazier uses low quality gas and raw materials to stably produce iron.
