Vortex chamber body for metal melting furnace, and metal melting furnace using said vortex chamber body

摘要

[Problem] To be able to prevent accidents, easily perform maintenance, and simplify the configuration. [Solution] The present invention is provided with: a furnace main body having a storage space for storing a me a vortex chamber body having a vortex chamber capable of connecting to the storage space of the furnace main body; and a weir part for connecting/disconnecting the storage space and the vortex chamber. The weir part is provided with a blind weir part and an opened weir part which are independent from one another. At least the blind weir part is configured so as to be able to move upward and downward relative to the vortex chamber body, and the connection/disconnection is performed by switching between the upward movement position and the downward movement position. The opened weir part has a notch for connecting the vortex chamber and the storage space in the connected state.
