Description
Изобретение относитс к области ферросплавного производства.This invention relates to the field of ferroalloy production.
Известен способ получеип ферровольфрама , заключающийс в проплавлеиии вольфрамового концентрата, довосстановлеиии получеииого шлака ферросилицием и рафинировании сплава вольфрамовым концентратом.The known method of obtaining ferro-tungsten consists in the melting of tungsten concentrate, the reduction of the obtained slag by ferrosilicon, and the refining of the alloy with tungsten concentrate.
С целью снижени содерлсанн меди в ферровольфраме и улучшени технико-экономических показателей процесса при использовании медистого вольфрамсодержащего материала , например буровых короиок, сплав после довосстаиовлени шлака обрабатывают смесью сернокислого натри и плавикового шпата, вз тых в соотиошении (1:0,5) - (1:1), а затем рафинируют высокоосновным шлаком. Пример. Отвальный шлак от производства ферровольфрама довосстанавливают ферросилицием , под ним проплавл ют медьсодержащие материалы (буровые коронки) и обрабатывают смесью сернокислого натри и плавикового шпата дл удалени меди. После этого выпускают шлак с содержанием 8% серы и 4,8% меди. Оставшийс в печи сплав с содержанием (J 10% вольфрама, 8--10% кремни , 0,08-0,10% меди, 1-2,5% серы, остальноежелезо рафинируют высокоосиовным шлаком от серы и выпускают шлак. Далее рафинируют сплав от кремни и других примесей вольфрамовым концентратом.In order to reduce copper content in ferro-tungsten and improve the technical and economic performance of the process using copper tungsten-containing material, such as drill bits, the alloy after slag mastering is treated with a mixture of sodium sulfate and fluorspar, taken in a ratio of (1: 0.5) - (1 : 1), and then refined with highly basic slag. Example. The waste slag from the production of ferro-tungsten is made up by ferrosilicon, copper-bearing materials (drill bits) are smelted underneath and treated with a mixture of sodium sulfate and fluorspar to remove copper. After that, slag is produced with a content of 8% sulfur and 4.8% copper. The remaining alloy in the furnace contains (J 10% tungsten, 8-10% silicon, 0.08-0.10% copper, 1-2.5% sulfur, the rest of the iron is refined with high-axial slag from sulfur and the slag is released. Then the alloy is refined from silicon and other impurities tungsten concentrate.
Полученный ферровольфрам, содержащий 72% вольфрама. 0,2% кремни , 0,15% меди, 0.08% серы, вычерпывают из печи.The resulting ferro-tungsten containing 72% tungsten. 0.2% silicon, 0.15% copper, 0.08% sulfur, scoop out the furnace.

Способ Бынлавки ферровольфрама, включающий довосстаноБление шлака ферросилицием , рафинирование снлава вольфрамовым концентратом , отличающийс тем, что с целью снижени содержани меди в ферровольфраме и улучшени технико-экономических показателей процесса при использовании медистого вольфрамсодержащего материала, сплав иосле довосстановлени шлака обрабатывают смесью сернокислого натри и илавикового шпата, вз тых в соотношении (1:0,5) - (1:1), а затем рафинируют высокоосновным шлаком.The method of ferro-tungsten bins, including the addition of slag by ferrosilicon, refining of the melt with tungsten concentrate, characterized in that, in order to reduce the copper content in ferro-tungsten and to improve the technical and economic indicators of the process when using copper-containing tungsten-containing material, the alloy and pulp were removed. taken in the ratio (1: 0.5) - (1: 1), and then refined with highly basic slag.
