STEEL MELTING BRIQUETTE Russian patent published in 2007 - IPC C22B1/243

Abstract RU 2304175 C2

FIELD: ferrous metallurgy, particularly briquetting and usage of iron containing waste materials.

SUBSTANCE: briquette contains scale of ferrous metal, blast furnace dust, dust of scrubbing of electric steel melting production and cement as binder. Briquette contains next relation of components, mass %: dust of scrubbing of electric steel melting production, 10 - 60; blast furnace dust, 0.5 - 15; ferrous metal scale, 35 -80; cement, 1 - 4.5.

EFFECT: less loss of yield, enhanced strength of briquettes, possibility for recovering steel production waste, good frothing properties of slag, increased degree of dephosphorization.
