Claims (3)

1. Способ получения феррониобия внепечной восстановительной плавкой, заключающийся в приготовлении шихты, восстановлении окислов ниобия и железа порошком алюминия, отличающийся тем, что для снижения содержания серы и фосфора в сплаве феррониобия в тигли послойно вводят шихту и измельченный до крупности шихты шлак от предыдущих плавок в количестве до 6-8% от веса шихты.1. A method of producing ferroniobium with out-of-furnace reducing smelting, which consists in preparing a charge, reducing niobium and iron oxides with aluminum powder, characterized in that, in order to reduce the sulfur and phosphorus content in the ferroniobium alloy, the mixture is layered into the crucibles and the slag crushed to the size of the mixture from previous melts into the amount of up to 6-8% of the weight of the mixture. 2. Способ по п.1, отличающийся тем, что плавку ведут в массивных толстостенных разборных медных тиглях, состоящих из четырех частей.2. The method according to claim 1, characterized in that the melting is carried out in massive thick-walled collapsible copper crucibles, consisting of four parts. 3. Способ по п.1, отличающийся тем, что плавку ведут в медном тонкостенном разборном водоохлаждаемом тигле.3. The method according to claim 1, characterized in that the melting is carried out in a copper thin-walled collapsible water-cooled crucible.
