Изобретение относитс к производству ферросплавов. В насто щее врем стандартный феррониобий и ниобиевые сплавы получают на технической п тиокиси ниоби или из концентратов, отвечающих требовани м стандартов, углетермическим и алюминиотермическим способом llОсобенностью этих способов вл етс высокое требование к чистоте ниобиевогоThe invention relates to the production of ferroalloys. Nowadays, standard ferroniobium and niobium alloys are produced on technical niobium pentoxide or from concentrates that meet the requirements of standards, by the coal thermal and aluminum thermal methods. A special feature of these methods is the high purity requirement of niobium
сырь по фосфору, поскольку последний вphosphorus feedstocks since the last
процессе восстановлени полностью переходит в сплав.the reduction process is completely transformed into the alloy.
В то же врем имеютс ниобийсодержа- щие руды, в том числе и крупных месторождений на Востоке Советского Союза, со держащие большое количество фосфора, который не удал етс обычными методами обогащени .At the same time, there are niobium-containing ores, including large deposits in the East of the Soviet Union, containing a large amount of phosphorus, which is not removed by conventional enrichment methods.
Гидрометаллургическое обогащение дорого и нетехнологично.Hydrometallurgical enrichment is expensive and low-tech.
Ниобиевые концентраты ( содержат 1-4% фосфора вместо О,О8-0,12% по норме (МПТУ 442 3-54). Это не позвол ет получать из них стандартные ниобиевые сплавы существующими способами.Niobium concentrates (contain 1–4% phosphorus instead of O, O8–0.12% in normal (MPTU 442 3-54). This does not allow obtaining standard niobium alloys from them using existing methods.
Рекомендаци проведени процесса восстановлением вредных примесей химически активным восстановителем, каким вл етс алюминий, ведет к потер м ниоби от его восстановлени и выводе из щдакового расплава в блок попутного металла на первой стадии (безвозвратные потери).The recommendation of carrying out the process of restoring harmful impurities with a chemically active reducing agent, such as aluminum, leads to the loss of niobium from its reduction and removal from the schdak melt to the associated metal in the first stage (irretrievable losses).
Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс способ получени малофосфористых шлаков, основанный на селективном углетермическом восстановлении фофора и железа при оптимальном количестве углерода 0,18-0,20 на единицу марганца 2.The closest to the proposed technical essence and the achieved result is a method for producing low-phosphorus slags, based on selective coal-thermal reduction of phosphorus and iron with an optimal amount of carbon 0.18-0.20 per unit of manganese 2.
Содержание фосфора в исходной марганцевой руде - 0,15%, в обесфосфоренных шлках - 0,015% фосфора.The phosphorus content in the original manganese ore is 0.15%, in the phosphorus-free slags it is 0.015% phosphorus.
Фосфор в обесфосфоренных шлаках остаес за счет не осевщих корольков фосфористого металла, полученного в процессе восстановительной плавки первого этапа.Phosphorus in the free phosphorus slags remains due to the non-settling cores of the phosphorous metal obtained in the process of reduction smelting of the first stage.
Полученный щлак I этапа проплавл ют на втором этапе в электропечах с целью получени либо марганца (предельного) угThe obtained slag of the first stage is melted at the second stage in electric furnaces with the aim of either obtaining manganese (limit) carbon
