СПОСОБ ИЗВЛЕЧЕНИЯ ВАНАДИЯ ИЗ ЧУГУНАMETHOD OF EXTRACTING VANADIUM FROM CHUGON

За влено 5 окт бр  1940 г. за № 303094 Народный Комиссариат черной металлурлни СССРIt was announced on Oct. 5, 1940, under No. 303094 People's Commissariat of Ferrous Metallurgy of the USSR

Описываемый способ извлечени  ванади  из чугуна путем окислени  ванади  и последующей переработки ванадиевого шлака отличаетс  из известных тем, что, с целью .получени  малофосфористого и маложелезистого шлака, передел ванадистых чугунов и получение ванадиевых шлаков ведут к вагранке.The described method of extracting vanadium from cast iron by oxidizing vanadium and subsequent processing of vanadium slag differs from those known in order to obtain low-phosphorous and low-iron slag, the redistribution of vanadist iron and the production of vanadium slag lead to a cupola.

При малом абсолютном количестве ваграночного шлака (от 3 до 8%) и высоком угаре ванади  (80-90% от содержащегос  в чугуне) при плавке в вагранке получают шлак с высокой концентрацией п тиокиси ванади  (до 15%) и низким содержанием закиси железа (2-10%).With a small absolute amount of cupola slag (from 3 to 8%) and high vanadium carbon monoxide (80-90% of the contained in the cast iron), when melting in the cupola, slag is obtained with a high concentration of vanadium pentoxide (up to 15%) and low iron oxide content ( 2-10%).

Из ваграночного ванадиевого шлака в доменной печи при повышенной температуре горна получаетс  феррованадий с содержанием от 15 до 45% ванади ; при плавке ваграночного ванадиевого шлака в домне в шихту могут вводитьс  и другие материалы - металлические добавки: руды, флюсы, отходы и т. и.From cupola vanadium slag in a blast furnace at elevated furnace temperature, ferrovanadium is obtained containing from 15 to 45% vanadium; when melting cupola vanadium slag in the blast furnace, other materials can also be introduced into the mixture — metal additives: ores, fluxes, waste, etc., and so on.

Ванадиевый ваграночный шлак может быть также использован как сырье дл  получени  феррованади  обычными методами; при этом желательно часть окиси кальци  в шлаке заменить окисью магни .Vanadium cupola slag can also be used as a raw material for the production of ferrovanadium by conventional methods; however, it is desirable to replace part of calcium oxide in the slag with magnesium oxide.

Способ особо -пригоден дл  извлечени  из чугунов с низким содержанием этого элемента.The method is particularly suitable for extraction from cast iron with a low content of this element.

Предмет изобретени Subject invention

Способ извлечени  ванади  из чугуна путем окислени  ванади  и последующей переработки ванадиевого шлака, отличающийс  тем, что, с целью получени  малофосфористого и маложелезистого, шлака, передел ванадистых чугунов и получение ванадиевых шлаков ведут в вагранке.A method of extracting vanadium from iron by oxidation of vanadium and the subsequent processing of vanadium slag, characterized in that, in order to obtain low-phosphorous and low-iron, slag, the redistribution of vanadist iron and the production of vanadium slag is conducted in a cupola.
