BURDEN FOR PRODUCTION OF AGGLOMERATE Russian patent published in 2006 - IPC C22B1/16 

FIELD: ferrous metallurgy; production of agglomerate and preparation of iron ore raw material for metallurgical process stage.

SUBSTANCE: proposed burden contains iron ore concentrate, iron-containing material, lime stone, solid fuel and vanadium-containing metal product of processing metallurgical slag dumps. Ratio of ingredients in burden is as follows, mass-%: iron-containing material, 15-40; limestone, 3-8; solid fuel, 4-7; vanadium-containing metal product of processing slag dumps, 4-12; the remainder being iron ore concentrate. Size of vanadium-containing metal product is up 10 mm. Used as iron-containing material are metallurgical dust and agglomeration and blast furnace returns.

EFFECT: reduced content of expensive iron ore concentrates in agglomerate burden; reduced consumption of solid fuel at retained strength characteristics.
