Description
Изобретение относитс к области черной металлургии. Известен способ получени сил.икомарганца, заключающийс в проплавлении шихты, состо щей из кварцита, марганецсодержащего материала и кокоика. Предложенный способ отличаетс тем, что, с целью повьппени извлечени марганца, в щихту периодически через 3-20 м,ин загружают смесь карбида кремни и железа. Соотнощение карбида кремни и железа в смеси составл ет (1 :0,1) - (1 : 0,9). Пример. Выплавку сили-комарганца производили в дуговой одноэлектродной электропечи с провод щей гГодиной и мощностью трансформатора 80 ква. В печь непрерывно загружали шихту, состо щую из 4,5 кг марганцевого концентрата, 1,1 кг кварцита, 1,3 кг коксика и 0,3 кг доломита (на одну колошу). Периодически через одну загрузку вместо 0,6 кг кварцита и 0,4 кг кокснка в шихту вводили смесь из 0,4 кг карбида кремни и 0,2 кг железной стружки. В резу.тьтате извлеченпе марганца повысилось до 93%, расход энергии снизилс на 6,3%. Предмет изобретени 1.Способ получени силикомарганца, заключающийс в проплавлении шихты, состо щей из марганецсодержащего материала, углеродистого восстановител и кварцита, отличающийс тем, что, с целью повышени извлечени ма|рганца, в шихту периодически через 3-20 мин загружают смесь карбида кремни и железа. 2.Способ по п. 1, отличающийс тем, что в смеси соотношение карбида кремни и железа равно от 1 : 0,1 до 1 : 0,9.This invention relates to the field of ferrous metallurgy. A known method for producing silcano manganese consists in the melting of a mixture consisting of quartzite, manganese-containing material and cocoic. The proposed method is characterized in that, in order to further extract manganese, in a mixture periodically after 3-20 m, a mixture of silicon carbide and iron is injected. The ratio of silicon carbide and iron in the mixture is (1: 0.1) - (1: 0.9). Example. The smelting of co-manganese was produced in a single-arc electric furnace with a conductive gas and a transformer capacity of 80 kVA. A mixture consisting of 4.5 kg of manganese concentrate, 1.1 kg of quartzite, 1.3 kg of coke and 0.3 kg of dolomite (per one pile) was continuously loaded into the furnace. Periodically, through a single load instead of 0.6 kg of quartzite and 0.4 kg of coxnack, a mixture of 0.4 kg of silicon carbide and 0.2 kg of iron shavings was introduced into the mixture. As a result, manganese was recovered increased to 93%, energy consumption decreased by 6.3%. The subject of the invention 1. A method for producing silicomanganese, which involves melting a mixture consisting of a manganese-containing material, a carbonaceous reducing agent and quartzite, characterized in that, in order to increase the extraction of manganese, a mixture of silicon carbide and gland. 2. A method according to claim 1, characterized in that the mixture ratio of silicon carbide and iron is from 1: 0.1 to 1: 0.9.
