The invention discloses a novel 
vacuum furnace automatic 
revolving door which comprises a furnace door, a furnace door 
cantilever, a furnace door rotating shaft, gear motors and a 
control system, wherein the furnace door, the furnace door 
cantilever, the furnace door rotating shaft, the gear motors and the 
control system are mounted on a furnace body. The 
control system comprises a central controller and a 
servo controller, one end of the furnace door 
cantilever is fixedly connected with the furnace door, and the other end of the furnace door cantilever is fixedly connected with the furnace door rotating shaft in a rotating mode. The furnace door rotating shaft is connected with the gear motors, and the gear motors drive the furnace door rotating shaft to rotate along the ends connected with the gear motors. The 
servo controller is connected with the gear motors, the 
servo controller is connected with the central controller, and the central controller controls the gear motors through the servo controller to drive the furnace door rotating shaft to slowly rotate at the initial stage and the final stage so as to drive the furnace door to be slowly opened and closed. The novel 
vacuum furnace automatic 
revolving door can be automatically opened, and opening or closing safety and stability of the furnace door can be guaranteed.
