Background technique [0002] Rare earth permanent magnet materials are used more and more for their excellent magnetic properties, and are widely used in medical nuclear magnetic resonance imaging, mobile phone electroacoustic and camera modules, micro motors for automobiles, energy-saving air conditioners, servo motors, and new energy vehicles. Driving motors, wind power generation and other application fields. [0003] There are generally two methods for making rare earth perm...

AI Technical Summary

Problems solved by technology

However, the above-mentioned vacuum smelting quick-setting furnace still adopts the feeding method of filling the main quick-setting alloy raw materials into the melting crucible at one time in the atmospheric environment, which does not solve the problem that the rare earth raw materials are easily oxidized, resulting in slagging and serious waste of rare earth raw materials. On the other hand, since the vacuum smelting quick-setting furnace of the prior art still belongs to the single-chamber furnace in essence, it is necessary to open the furnace cover to destroy the vacuum environment in the furnace to carry out the loading of the alloy raw material after casting the alloy sheets of each furnace. It seriously affects the production efficiency. In addition, the frequent exposure to the atmosphere in the melting and casting work area also has a certain impact on the life and working stability of core components such as water-cooled rollers and melting crucibles.
