Process for the production of carburized sponge iron briquettes

In the direct reduction of iron ore in a series of fluidized beds, for the production of carburized iron sponge briquettes for use in electric furnaces, carburization is carried out after the last fluidized bed, at a temperature of 600 DEG to 700 DEG C., by batching the reduced iron powder with a so...

Zusammenfassung:In the direct reduction of iron ore in a series of fluidized beds, for the production of carburized iron sponge briquettes for use in electric furnaces, carburization is carried out after the last fluidized bed, at a temperature of 600 DEG to 700 DEG C., by batching the reduced iron powder with a solid finely divided carbonaceous material and then briquetting the mixture, in an inert atmosphere.
