METHOD AND DEVICE FOR PRODUCTION OF MOULDED PRODUCTS Russian patent published in 2015 - IPC C21B13/00 

FIELD: process engineering.

SUBSTANCE: invention relates to method and device for production of compacted articles containing directly reduced fine iron (DRI) for reduction in fluidized bed for direct reduction of aforesaid iron. Said DRI obtained in unit (1) for reduction in fluidized bed at direct reduction is pelletized to get compacted articles (8). Dry fine material is admixed to said DRI and contains fine ion ore (2) as well as fine iron and carbon. Quantitative portion of fry fine material in the mix features inferior limit of 0.25 wt %, preferably 0.5 wt %, and makes up to 10 wt %, preferably, up to 5 wt %.
