| 摘要 |
The invention relates to a method and to a system for producing pig iron or fluid steel pre-products, wherein charge materials comprising iron ore and additive materials are at least partially reduced in a reduction zone by means of a reduction gas, subsequently introduced into a melting zone and melted under supply of carbon carriers and oxygen-containing gas under formation of said reduction gas. The reduction gas formed in the melting zone is supplied to the reduction zone and there converted and removed as export gas, COis separated from the export gas and a product gas is formed that is used for insertion of powder-shaped carbon carriers in the melting zone. |
