Description
Безуглеродистый лром или феррохром получают вакуумтермическим отжигом углеродистого хрома и феррохрома с восстановителем .Carbon-free lromium or ferrochrome is produced by vacuum-thermal annealing of carbon chromium and ferrochrome with a reducing agent.
Описываемый способ отличаетс от известного тем, что отжигу подвергают смесь силикохрома с содержанием кремни более 15% с хромсодержащими материалами, вз тыми в количестве, достаточном дл св зывани кремни и углерода в силикохроме.The described method differs from the known one in that it is subjected to annealing a mixture of silicochrome with a silicon content of more than 15% with chromium-containing materials taken in an amount sufficient to bind silicon and carbon in silicochrome.
В злектродуговой печи из хромсодержащего сырь , кремнезема и углеродсодержащего восстановител выплавл ют силикох.ром с содержанием кремни более 15%. После измельчени до 0,1 мм металлический продукт плавки смешивают с хромсодержащими материалами с таким расчетом, чтобы св зат кремний и углерод, содержащиес в оилико хроме. Получившуюс шихту после брикетировани подвергают вакуумтермическому от жигу при1300-1350° С.In an arc-arc furnace, the chromium-containing raw material, silica, and carbon-containing reductant are smelted with a silicon oxide with a silicon content of more than 15%. After grinding to 0.1 mm, the metal smelting product is mixed with chromium-containing materials so as to bind the silicon and carbon contained in the iron chrome. The resulting mixture after briquetting is subjected to vacuum thermal burning from 1300-1350 ° C.
