FIELD: production of ferrosilico-aluminum in ore heating furnace of silicon- and aluminum- containing material.
SUBSTANCE: method comprises steps of using coal -containing rock with carbon content 5 -35 % as silicon- and aluminum-containing material. Melting is realized while keeping during process lack of carbon in charge loaded to furnace in range consisting 3 -12% of stoichiometric quantity due to adding coke and (or) quartzite to coal containing rock. Invention provides stabilized process of melting out silicon-aluminum alloys with aluminum content 5 -35%.
EFFECT: enhanced technical and economical factors of ferrosilico-aluminum production, elimination of carbide formation and crumbling of alloy.
