Изобретение относитс к черной металлургии и может быть использовано дл легировани стали и сплавов в процессе их выплавки .The invention relates to ferrous metallurgy and can be used for the alloying of steel and alloys in the process of their smelting.
Известна смесь, состо ща из порошкообразных отходов (например, ферросилици и карборунда), содержащих до 90% Si и органической св зки типа силиконовой.A mixture of powdered waste (e.g., ferrosilicon and carborundum) containing up to 90% Si and an organic type silicone binder is known.
Однако применение такой смеси не обеспечивает высокого использовани кремни , значительна часть которого бесполезно расходуетс на восстановление окислов щлака. С целью повышени степени полезного использовани кремни в предлагаемую смесь ввод т хромовую руду при следующем соотношении компонентов, вес.%:However, the use of such a mixture does not ensure the high use of silicon, much of which is wasted on the reduction of oxides of slag. In order to increase the usefulness of silicon, chromic ore is introduced into the proposed mixture in the following ratio of components, wt.%:

As the mixture melts, chromium oxides are reduced by silicon, ferrosilicochrome and carborundum. Carborundum carbon is also involved

The resulting bubbles of CO carry out local micromixing in the layer of the molten mixture, accelerating the reaction processes inside it.

Последний становитс более кислым и в зким, преп тству контакту основного шлака с металлом, а следовательно , и угару х;рома и .кремни за счет окислов, содержащихс в основном щлаке.1 Restored chromium is absorbed by the metal, and the reaction product is absorbed by silica in the neutral slag mixture. The latter becomes more acidic and viscous, preventing the contact of the main slag with the metal and, therefore, the carbon, rum, and silica due to the oxides contained in the primary slag.
