Abstract

1. Способ производства химически активных металлов, включающий нагрев реакционной шихты в присутствии восстановителя, восстановление на катоде металла и на аноде кислорода, отличающийся тем, что шихту не требуется формировать в электрод, так как она поступает в ракционную зону через внутреннюю полость графитового электрода, который служит одновременно анодом, а процесс восстановления металла складывается из следующей цепочки: постепенный нагрев восстанавливаемой шихты внутри электрода, металлотермическое восстановление металла внутри электрода, металлотермическое, плазменнохимическое и электрохимическое восстановление металла в зоне горения дуги, образование ванны металла и его охлаждение на катоде, которым является кристаллизатор. ! 2. Устройство для производства химически активных металлов, содержащее кристаллизатор, электрод, корпус, подающее шихту механическое устройство, бункер, патрубок, отличающееся тем, что кристаллизатор подключен к отрицательному полюсу и является катодом, а электрод - к положительному и является анодом, причем электрод выполнен с центральным отверстием, через которое перемещается шихта в кристаллизатор за счет механического устройства, расположенного внутри бункера. ! 3. Устройство по п.2, отличающееся тем, что кристаллизатор выполнен в виде конуса или полусферы, а патрубков два для отдельного создания вакуума или подачи газа в бункер и корпус устройства.1. A method for the production of chemically active metals, including heating the reaction mixture in the presence of a reducing agent, reducing the oxygen at the metal cathode and anode, characterized in that the mixture does not need to be formed into the electrode, since it enters the cancer zone through the internal cavity of the graphite electrode, which serves as an anode at the same time, and the metal reduction process consists of the following chain: gradual heating of the recoverable charge inside the electrode, metallothermal metal reduction inside At the electrode, metallothermal, plasma-chemical and electrochemical metal reduction in the arc burning zone, the formation of a metal bath and its cooling at the cathode, which is a crystallizer. ! 2. A device for the production of chemically active metals, containing a crystallizer, an electrode, a housing, a mechanical feed device, a hopper, a nozzle, characterized in that the mold is connected to the negative pole and is the cathode, and the electrode is connected to the positive pole and is the anode, and the electrode is made with a central hole through which the charge moves into the mold due to a mechanical device located inside the hopper. ! 3. The device according to claim 2, characterized in that the mold is made in the form of a cone or a hemisphere, and two nozzles for separate creation of vacuum or gas supply to the hopper and the housing of the device.
