Description
Изобретение относитс к ферросплавному производству.This invention relates to ferroalloy production.
Известны способы получени ферробора и ферроборала внепечиой и электропечной плавкой. Как в том, так и в другом способе проплавл ют смесь боратовой руды, железной окалины и алюминиевый порошок. При этом примеси: фосфор, сера и др.-усваиваютс сплавом. Кроме того, извлечение бора при внепечной плавке даже с учетом применени железотермического осадител составл ет около 70%, а нри электропечной плавке находитс на уровне 50%.Methods are known for producing ferroboron and ferroboral by non-furnace and electric fusion. In both methods, a mixture of borate ore, iron oxide and aluminum powder is smelted. At the same time, impurities: phosphorus, sulfur, and others are assimilated by the alloy. In addition, the extraction of boron during secondary smelting, even taking into account the use of an iron-thermal precipitator, is about 70%, and electrofusion at a level of 50%.
Существующие способы характеризуютс высоки.м расходом алюмини . Алюминий ири внеиечной плавке расходуетс пе только по пр мому назначению - па восстановление целевого элемента, но и на побочное - в составе термитной смеси д.л нодогрева щихты и обеспечени необходимой температуры процесса. При этом алюминий восстанавливает и другие окислы руды, например, кремнезем , сульфаты и др.Existing processes are characterized by high aluminum consumption. The irradiated aluminum melting is consumed not only for its intended purpose — to restore the target element, but also to the secondary — as part of a thermite mixture for heating the furnace and ensuring the required process temperature. At the same time, aluminum restores other oxides of ore, for example, silica, sulphates, etc.
Цель предлагаемого изобретени - повысить извлечение бора, снизить расход алюмини и содержание примесей в сплаве.The purpose of the present invention is to increase the boron extraction, to reduce the consumption of aluminum and the content of impurities in the alloy.

After that, a mixture of calcium borates and aluminum is iodized into the molten metal. As a result of the alumina-thermal process, the reduced boron is dissolved in the metal melt, and the alumina with the oxide

The composition of the briquettes is adjusted in such a way as to ensure the production of standard waste and liquid slag, as well as the separation of liquid products.
