Abstract
1. Способ получения алюминиево-кремниевого сплава в электролизере для производства алюминия, включающий подачу в электролит фтористых солей, кислородсодержащего соединения алюминия и кремнефтористого натрия, отличающийся тем, что в качестве кислородсодержащего соединения алюминия используют глинозем и/или гидроокись алюминия, в электролит подают смесь кремнефтористого натрия и кислородсодержащего соединения алюминия при весовом соотношении 1:(1,5÷5,0) в пересчете на глинозем, а для подачи материалов в электролит используют установку автоматического питания электролизера. ! 2. Способ по п.1, отличающийся тем, что в качестве фтористой соли в электролит периодически подают фтористый алюминий. ! 3. Способ по п.1, отличающийся тем, что в качестве фтористой соли в электролит периодически подают фтористый кальций.1. A method of producing an aluminum-silicon alloy in an electrolytic cell for aluminum production, comprising supplying fluoride salts, an oxygen-containing aluminum compound and sodium silicofluoride to the electrolyte, characterized in that alumina and / or aluminum hydroxide is used as an oxygen-containing aluminum compound, and a mixture of silicofluoride is fed into the electrolyte sodium and oxygen-containing compounds of aluminum with a weight ratio of 1: (1.5 ÷ 5.0) in terms of alumina, and to supply materials to the electrolyte, use a Power-automatic cell. ! 2. The method according to claim 1, characterized in that aluminum fluoride is periodically fed into the electrolyte as the fluoride salt. ! 3. The method according to claim 1, characterized in that calcium fluoride is periodically fed into the electrolyte as the fluoride salt.
