| titleOfInvention | Method for producing molten pig intermediate product or molten steel intermediate product and sponge metal |
| abstract | The present invention relates to a method for producing molten pig iron (16) and sponge metal from a charge material containing iron ore (4) and metal ore, the charge material is directly reduced to sponge iron in at least one first reducing zone (2) The sponge iron is melted in the molten gasifier 15 by supplying the carbon medium 10 and the oxygen-containing gas, and CO- and H 2 -containing reducing gases are generated and supplied to the first reduction zone 2 to react. And then discharged to the top gas, and the discharged top gas is CO 2 removed and selectively heated after the cleaning action, and is supplied to at least one other reduction zone 27, at least most of which is CO 2 removed. The metal ore, in particular the iron ore 26 is directly reduced, and after reaction with the metal ore 26, is discharged to the exhaust gas and washed in the scrubber.n n n In order to utilize the sludge generated in the scrubber while consuming as little energy as possible, the sludge obtained during the top gas cleaning from the first reduction zone 2 is dehydrated and charged into the molten gasifier 15, while the other reduction zone 27 The sludge obtained during the off-gas cleaning of the () is dehydrated and supplied to the first direct reduction zone (2). |
