The invention discloses a sealed
smoke hood suitable for a rotary
electrode vacuum electroslag remelting technology. A
smoke hood body is connected with a lifting platform of a rotary
electrode vacuumelectroslag furnace in rotary
electrode vacuum electroslag remelting equipment through a
smoke hood suspension device arranged at the upper end of the
smoke hood body; a rotary shaft of a rotary electrode vacuum electroslag furnace in the rotary electrode vacuum electroslag remelting equipment penetrates through an upper end opening of the
smoke hood to enter the
smoke hood body, the lower portion of the smoke hood body is in
butt joint with a crystallizer of the electroslag furnace, a sealing sleeve is arranged on the upper portion of the smoke hood body, the upper end face where a pump-outpipeline is arranged and the side edge of the sealing sleeve are connected with of a vacumm pump of the rotary electrode vacuum electroslag furnace; and a water inlet
pipe and a water outlet
pipe arerespectively arranged at the upper part and the lower part of the side wall of the smoke hood body and communicate with a
water circulation system in the rotary electrode vacuum electroslag remeltingequipment. By improving the sealing smoke hood, the problems of rotating body sealing and vacuum environment sealing in a rotary electrode vacuum electroslag remelting
system are solved, the refiningeffect of an electroslag remelting process is improved, the structure is simple, and the sealing performance is good.
