BRIQUETTE FOR TOSSING OF BLAST FURNACE CRUCIBLE Russian patent published in 2004 - IPC

Abstract RU 2241759 C1

FIELD: iron metallurgy, in particular method for agglomeration of iron-ore feed.

SUBSTANCE: briquette for tossing of blast furnace crucible is produced by batch compacting under pressure of 500-1000 Mpa. Batch comprises oxidized iron-containing materials, manganese-containing materials and fluxing additives in amount to provide desired ratio of carbon, iron oxide, manganese oxide, calcium oxide, silica and alumina, namely: C:Fe, Mn:Fe, CaO:SiO2 MgO:Al2O3 are 0.05-0.15, 0.02-0.2, 0.6-1.2, 0.2-0.6, respectively. All materials used for briquette manufacturing, have fineness at most 1 mm, organic coupling agent is used as a binder (e.g. lignosulphonate or fatty acid slot).

EFFECT: briquette with improved functional and metallurgic characteristics.
