Снособ получени феррохромванади относитс к ферросплавному производству.The method for producing ferrochromvanadi relates to ferroalloy production.
Известен способ получени феррованади селективным рафинированием конвертер«0ГО шлака в электропечи с «получением на первой стадии промежуточного сплава и последующим его рафинированием под высокоосновным шлаком.A known method for producing ferrovanadium by selective refining of a converter of slag in an electric furnace with the production of an intermediate alloy in the first stage and subsequent refining under a highly basic slag.
Однако по этому способу )ванадий из шлака извлекаетс неполно.However, by this method) vanadium is not fully recovered from the slag.
С целью увеличени извлечени ванади предложено рафинирование промежуточного сплава вести п тиокисью ванади .In order to increase vanadium recovery, it has been proposed to refine the intermediate alloy with vanadium pentoxide.
Полученный в конвертере высокоосновный ванадиевый шлак подвергают размолу и магнитной сепарации дл отделени металловключений .The highly basic vanadium slag obtained in the converter is subjected to grinding and magnetic separation in order to separate the metallic inclusions.
Из шлака в электропечи выплавл ют промежуточный сплав типа ферросиликохромванадий , где в качестве основного восстановител примен етс углерод в виде коксовой мелочи или коксика с низким содержанием золы и фосфора. После полного восстановлени 01КИ1СЛов углеродом с целью снижени углерода в Сплаве повышают содержание кремни до 40%.An intermediate alloy of the ferrosilicochromanadium type is melted from the slag in an electric furnace, where carbon in the form of coke breeze or coke with a low content of ash and phosphorus is used as the main reducing agent. After the complete reduction of carbon with carbon dioxide to reduce carbon in the alloy, the silicon content is increased to 40%.
Полученный ферросиликохром(ванадий рафинируют п тиокисью ванади и высокоосноБным шлаком и выплавл ют из него феррохромванадий различных марок.The obtained ferrosilicochrome (vanadium is refined with vanadium pentoxide and high-sulfur slag and various brands of ferrochromo- vanadium are smelted from it.
Предмет изобретени Subject invention
Способ получени феррохромванади , заключающийс в выплавке промежуточногоThe method of producing ferrochrome vanadium, which consists in smelting the intermediate
сплава типа ферросиликохромванадий, рафинировании его и последующем переплаве на феррохромванадий, отличающийс тем, что, с целью увеличени извлечени ванади , рафинирование промежуточнОГО сплава ведут п тиокисью ванади .an alloy of the ferrosilicochromanadium type, its refining and subsequent remelting to ferrochrome vanadium, characterized in that, in order to increase the recovery of vanadium, the refining of the intermediate alloy is carried out with vanadium pentoxide.
