PROCEDURE FOR PRODUCTION OF AGGLOMERATE Russian patent published in 2010 - IPC C22B1/16

Abstract RU 2406770 C2

FIELD: metallurgy.

SUBSTANCE: procedure consists in loading agglomerating machine with charge composed of iron ore material, flux, additives, sinter return and solid fuel, in igniting, agglomerating, cooling and mechanical treatment of cake with crumbling and screening. Also there is controlled and changed value of ratio of weight-average size f_wa to equivalent size on surface of f_ae of produced agglomerate, while maintaining ratio f_wa:f_ae within the range 1.0-2.0.

EFFECT: production of agglomerate with optimal value of average size and high physical properties most fully meeting requirements of blast furnace production to size.
