Abstract

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.

Description

technical field [0001] The invention relates to a rotary electrode vacuum electroslag remelting equipment, in particular to a sealed smoke hood suitable for the rotary electrode vacuum electroslag remelting technology. Background technique [0002] Traditional electroslag remelting is to pass current into the static consumable electrode in an open atmosphere, rely on the Joule heat generated in the slag pool to melt the consumable electrode, and the formed metal droplets pass through the slag pool to be refined and reach The bottom of the crystallizer is solidified into steel ingots under the action of cooling water. Electroslag remelting technology can improve the cleanliness of metals and obtain high-quality ingots with dense structures, but excessive power consumption, low production efficiency and higher refining efficiency requirements also restrict the development of electroslag remelting. [0003] In order to improve the electroslag remelting process, the researchers...
