METHOD OF MANUFACTURING CHROMIUM BRIQUETS FOR PRODUCING FERROCHROME Russian patent published in 1997 - IPC

Abstract RU 2083693 C1

FIELD: metallurgy. SUBSTANCE: invention concerns preparing charge materials for producing ferroalloys, in particular, ferrochrome. Chromium briquets are manufactured by way of dispensing chromium- containing component and binding agents, agitation, briquetting, and drying. As chromium-containing component, dust caught in gas treating system in the course of smelting ferrochrome is used, which is kept to decrease its volume by 10-20%, treated in mixer with water taken in amount 5-10% on dust weight, whereupon briquets are aerated when dried under natural conditions. EFFECT: increased stability of briquets in ferrochrome smelting process in refining or ore-reduction furnaces, which improves ferrochrome production parameters.
