Изобретение относитс  к области чернен металлургии;This invention relates to the field of ferrous metallurgy;

Изйестен способ рафинировани  ферросйлиий , закЛюча1ои;ийс  в обработке его хлорагентами вне иели.Izjesten is a method of refining ferrosilium, closed with the use of chlorine agents outside the field.

Дл  более полного удалени  алюмини  и титана из ферросилици , а также улучшени  условий иротека 1и  процессов выилавки ферросилици  предложен способ рафинировани  сплава хлорагентами, отличающийс  тем, что он совмещен с выплавкой ферросилици . Рафинирование ферросилици  хлорагентами в процессе его выплавки дает возможность вводить хлориды натри , кали  и магни  с коксом, опускованиой щихтой или непосредственно в реакционные тигли, что способствует лучшему контакту с окислами алюмини  и титана и, следовательно, более полному удалению их из ферросилици  в виде летучих хлоридов.For a more complete removal of aluminum and titanium from ferrosilicon, as well as to improve the conditions of the process and the processes of ferrosilicon extraction, a method has been proposed for refining the alloy with chlorine agents, characterized in that it is combined with smelting of ferrosilicon. The refining of ferrosilicon by chlorine agents during its smelting makes it possible to introduce sodium, potassium, and magnesium chlorides with coke, dipping it with a binder or directly into reaction crucibles, which promotes better contact with aluminum and titanium oxides and, therefore, more completely remove them from the ferrosilicon in the form of volatile chlorides .

Стабилизаци  электрической дуги в присутствии ионов натри , кали  и магни , а также понижение в кости кремнеземистого шлака окислами этих металлов способствует протеканию процессов выилавки ферросилици .Stabilization of the electric arc in the presence of sodium, potassium and magnesium ions, as well as the reduction of silica slag in the bone with oxides of these metals, facilitates the process of ferrosilicon extraction.

Пример. В качестве примера приводитс  рафинировка ферросилици  в процессе его выплавки в закрытой руднотермической печи.Example. As an example, the refining of ferrosilicon in the process of its smelting in a closed ore-smelting furnace is given.

Хлориды, вводимые, 1 аиример, в виде нонаренной соли, карналита и сильвинита, проход  вместе с пш.хтовыми материалами, постепенно нагреваютс , плав тс  и пропитывают кокс и глинистую примазку кварцило. При температуре 1500°С. происходит их взаимодействие с окислами алюмини  и титана с образованием летучих хлоридов - А1С1з, TiClo, TiCl.i, имеющих низкую температуру возгонии - 130-180° С. Последние удал ютс  совместно с колошниковыми газами и осаждаютс  в аппаратах газоочистки, которыми оборудованы закрытые печи.The chlorides introduced, 1 airimer, in the form of non-boiled salt, carnilit and sylvinite, the passage, along with hard household materials, gradually heated, melted and impregnated with coke and quartzilo adhesives. At a temperature of 1500 ° C. they interact with aluminum and titanium oxides with the formation of volatile chlorides - A1Cl3, TiClo, TiCl.i, having a low sublimation temperature - 130-180 ° C. The latter are removed together with blast gases and precipitated in gas-cleaning apparatuses with which closed furnaces are equipped.

Предмет изобретен и  The subject is invented and

1.Способ рафинировани  ферросилици  хлорагентами, отличающийс  тем, что, с целью удале)1и  алюмини  и титана, неносредственно в процессе и.тавки ввод т, по крайней мере, одно вещество из грунпы, содержащей хлориды натри , кали  и магни .1. A method of refining ferrosilicon with chlorine agents, characterized in that, in order to remove 1 and aluminum and titanium, at least one substance from the soil containing sodium, potassium and magnesium chlorides is introduced directly in the process and the packaging.

2.Способ ио п. 1, о т л и ч а ю щ и и с   тем, что хлориды }1атри , кали  и магни  ввод т с шихтой.2. The method of pp 1, about tl and h and y and with the fact that the chlorides} sodium, potassium and magnesium are introduced with the charge.

3.Способ по и. 1, о т л и ч а ю щ и и с   тем, что хлориды натри , кали  и магни  ввод т непосредственно в реакционные тигли.3. Method for and. 1, that is, with the fact that the chlorides of sodium, potassium and magnesium are introduced directly into the reaction crucibles.
