| titleOfInvention | A method of operating a vertical shaft moving bed reduction reactor for reducing iron ore to sponge iron |
| abstract | Process for operating a vertical moving bed reduction reactor for reducing iron ore to sponge iron with a reduction zone in the upper part of the reactor and a cooling zone in the lower part of the reactor, in which the desired degree of metallization of the reducing ore in the reduction zone and the desired degree of Cementation is obtained in the cooling zone, the method being characterized in that a predetermined flow of a reducing gas composed of carbon monoxide and hydrogen is fed into the reactor and in that the ratio of the reducing gas flow in the reduction zone to the reducing gas flow in the cooling zone is adjusted so that at least the The metallization taking place in the reduction zone and the cementing taking place in the cooling zone are changed, the carbon dioxide concentration in the reduction zone being adjusted to a value at which the desired degree of metallization is achieved there and at which the carbon dioxide content is achieved in the cooling zone to a value at which the desired degree of cementation in the cooling zone is obtained. |
