Description
Изобретение относитс к ферроспла вному производству в металлургии, в частности к металлургии феррованади , и может быть использовано при производстве высококачественного фер рэванади из ванад йсодержаадего сырь с повы енным содержанием марганца ,. Иэвестт способ вьшлавки фер юванади , вк.п|Ьча10щий периоды восстановлени и рафинировани . В первый период ведут восстановление ванади из его п тиокиси и оборотных проДук ов плавки (рафинировочный шпак) при избытке восстановител , во-второй рафинируют сплав от кремни дополнительными присадками п тиокиси ванади . Содержание в отвальном ишаке восстановительного периода ойд чно не превьпиает 0,35%. Во втором периоде обогащают сплав ванадием за счет восстановлени его кремний и алюминием из п тиокиси ванади , которую загружают в соотношении Isl. При снижении содержани кремни ниже 2% производ т: слив рафинировочного шпака,выпуск сплава из печи и разлив ку в чугунные изложницы. Рафинировоч ный шлак возвращают на следующую плавку дл довосстановлени 1. . Недостатком известного способа вл етс полученнРе феррованади с содержанием марганца от 2,5 до 5 Bfc.%. Такие концентрации марганца недбпустимы при производстве р да качественных марок ст,али и сплавов. - Высокое содержание марганца в сплаве обусловлено его содержанием в исходных материалах и весьма полным восстановлением металлов в восстановительный период. Цель изобретени - одновременное легированне сплава молибденом,- никелем или вольфрамом и удаление марганца . Цель достигаетс тем, что согласно известному способу получени феррованади , включающему восстановительный и рафинировочный периоды при металлотермическом производстве спла-г ва, выпуск из печи и разливку, в конце рафинировочного периода на расплав ввод т окислы (концентраты) легирующих элементов. Введение в сталь легирующих элементов в виде единого материала и расплавление их при одних температурах целесообразно дл обеспечени более равномерного распределени элементов в объеме стали.The invention relates to ferro-plating production in metallurgy, in particular to ferrovanadium metallurgy, and can be used in the production of high-quality ferro-vanadium from vanadium containing its raw materials with an increased manganese content,. Ivestt is a method of spinning the ferry of yuvadi, during the period of recovery and refining. In the first period, vanadium is reduced from its pioxide and circulating melting products (refining putty) with an excess of reducing agent; in the second, the silicon alloy is refined with additional additives of vanadium pentoxide. The content in the dump ass of the recovery period does not exceed 0.35%. In the second period, the alloy is enriched with vanadium due to its reduction with silicon and aluminum from vanadium pentoxide, which is loaded in the ratio Isl. While reducing the silicon content below 2%, the following was produced: refining shpak was drained, the alloy was released from the furnace and cast into cast iron molds. Refining slag is returned to the next melt for re-recovery 1.. The disadvantage of this method is to obtain ferrovanadium with a manganese content of 2.5 to 5 Bfc.%. Such concentrations of manganese are not acceptable in the production of a number of quality grades of steel, ali and alloys. - The high content of manganese in the alloy due to its content in the source materials and a very complete recovery of metals in the recovery period. The purpose of the invention is the simultaneous alloying of molybdenum alloy with nickel or tungsten and the removal of manganese. The goal is achieved by the fact that, according to a known method for producing ferrovanadium, which includes reduction and refining periods during metallothermic production of the alloy, discharging from the furnace and casting, oxides (concentrates) of alloying elements are introduced into the melt at the end of the refining period. The introduction of alloying elements into steel in the form of a single material and their melting at the same temperature is advisable to ensure a more uniform distribution of elements in the steel volume.
