| titleOfInvention | Production method of sponge iron |
| abstract | In the process of producing iron-containing materials by direct reduction, the synthesis gas is mixed with the top gas formed in the direct reduction of the iron oxide-containing material, and used as a CO- and H 2 -containing reducing gas to directly reduce and The iron oxide containing material is heated to the reduction temperature.n n n In order to save energy in an economically efficient manner, especially during steelmaking, direct reduction is carried out as follows:n n n In addition to reducing gases, gases containing carbon-containing gases such as natural gas or high-grade hydrocarbons are used for the reduction,n n n The iron oxide-containing material is exposed to reducing gas and additionally supplied carbon-containing gas for a predetermined period of time beyond the period necessary for complete reduction,n n n The CO / CO 2 ratio in the reducing gas is adjusted in the range of 2 to 5, preferably at least 2.5. |
