A method for producing an iron sponge |
| abstract |
A process for producing an iron sponge by direct reduction from an iron oxide-containing particulate material, wherein the reducing gas formed in the melt gasifying zone from the carbon carriers and the oxygen-containing gas is introduced into a reducing zone in which the iron oxide-containing material is located it consists of a combination of the following features: a reducing gas is introduced into the reduction zone, which contains N.sub.3.n. between 20 and 100 g of dust, and having a carbon content of between 30 and 70% by weight, and the iron oxide containing material being exposed to the reducing gas for a time lag that exceeds the time required for reduction. The process of the invention makes it possible to produce an iron sponge with an increased carbon content |
