Изобретение относитс к области производства ферросплавов.The invention relates to the production of ferroalloys.

Известеп способ рафинировани кремнистых сплавов, заключающийс в обработке сплава жидким шлаком, содержащим окислы щелочноземельных металлов и последующей продувке сплава сжатым воздухом.A known method of refining siliceous alloys involves the processing of an alloy with liquid slag containing oxides of alkaline earth metals and the subsequent blowing of the alloy with compressed air.

Предложенный способ отличаетс от известного тем, что с целью снижени содержани водорода в сплаве рафинировочный щлак предварительно смещивают с ферросплавом, содержащим менее 3% кремни . Дл повыщепи эффективности рафинировани в щлак перед рафинированием ввод т 1-5% карбида кальци .The proposed method differs from the known one in that in order to reduce the hydrogen content in the alloy, the refining slag is pre-biased with ferroalloy containing less than 3% silicon. To increase the efficiency of refining, 1-5% calcium carbide is added to the slag before refining.

Пример. Жидкий феррохромовый щлак с содержанием водорода 15 г смещивают с твердым дробленным феррохромом с содержанием хрома 72%, кремни 1,2%, железо остальное. Количество феррохрома составл ет 100 г на 200 г щлака. После выдержки при температуре 1750°С в течение 5 мин содержание водорода в щлаке составл ет 2 г. В щлак перед рафинированием ввод т промыщленный карбид кальци в количестве 2 г на 100 г щлака. После обработки полученным шлаком содержание водорода снизилось до 1,2 г.Example. Liquid ferrochrome shlak with a hydrogen content of 15 g is displaced with solid crushed ferrochrome with a chromium content of 72%, silicon 1.2%, iron the rest. The amount of ferrochrome is 100 g per 200 g of slag. After holding at a temperature of 1750 ° C for 5 minutes, the hydrogen content in the slag is 2 g. Into the slag before refining is added 2 mg of calcium carbide in an amount of 100 g of slag. After processing the resulting slag, the hydrogen content decreased to 1.2 g.
