Изобретение относитс к ферросплавному производству.This invention relates to ferroalloy production.
Известен способ получени ванадиевых сплавов, включающий селективное восстановление железа и восстановление из обогащенного шлака ванади кремнием ферросицили .A method of producing vanadium alloys is known, which includes the selective reduction of iron and the reduction of ferrosicyles from vanadium-rich enriched slag.
Предлагаемый способ отличаетс от известного тем, что железо восстанавливают иа смеси конвертерного шлака и углеродистого восстановител путем их обжига при температуре 900-ЮОО С; Это повышает содержание ванади в сплаве.The proposed method differs from the known one in that iron is reduced to a mixture of converter slag and carbonaceous reducing agent by calcining them at a temperature of 900 ° C; This increases the content of vanadium in the alloy.
Восстановление ванади из обогащенного шлака можно вести смешиванием его в ков-ше с кремнистым восстановителем с добавлением других легирующих элементов.The reduction of vanadium from enriched slag can be carried out by mixing it in a cov with a siliceous reducing agent with the addition of other alloying elements.
Например, из конвертерного, ,илака и нефт ного кокса пpигoтaвливaют гpaнyлы диаметром 5-7 мм и обжигают их в печи при( 1ООО°С в течение 2 ч. К обожженномуFor example, from the converter, sludge and petroleum coke, pellets are prepared with a diameter of 5-7 mm and burn them in a furnace at (1 ° C for 2 hours).
материалу добавл ют окись Кальци и расплавл ют при 155О С.Calcium oxide is added to the material and melted at 155 ° C.
Полученный обогащенный шлак восстанавливают кремнием ферросилици . В результате получают ванадиевый сплав с содержанием ванади 4О% и низким содержанием углерода и примесей цветных металлов.The resulting enriched slag is reduced by silicon ferrosilicon. The result is a vanadium alloy with a vanadium content of 4O% and low carbon content and non-ferrous metal impurities.
