The dust hood absorbs the dust and exhaust gas generated by the melting through a certain amount of air to achieve and improve the exhaust gas emission effect, and meets the requirements of the environmental protection environmental assessment requirements. The user can select the configuration according to the needs.

Cyclone dust hood: It has better vacuuming effect, takes up less space, can tilt forward and backward and stay in any position. Applicable to the fully automated feeding and discharging operations of the foundry. The biggest advantage of the cyclone dust hood compared to the traditional hydraulic tilting dust hood is that it can be tilted back and forth, and can be stopped at any position. The traditional vacuum hood can only stay in the front and rear two stations. When the stove worker operates, the cyclone type dust cover avoids the baking of the front cover to the operator and reduces the working intensity of the operator. The vacuum hood can effectively vacuum during the spheroidizing process before the furnace, which is not possible with the traditional vacuum hood. The dust hood is designed with a strong steel structure. The refractory cover is fixed in the middle of the dust hood. The vacuum hood can be adjusted to stop at any position. During the smelting process, the entire dust hood is in a closed position, and the furnace cover is covered on the molten pool raft to reduce heat loss during the feeding and smelting process, and the dust hood absorbs dust and exhaust gas through a certain amount of suction air. And improve exhaust emissions.

　It is connected to the exhaust gas discharge pipe system through a flange located on the rotating shaft of the furnace body. When the entire dust hood is opened in the forward direction, the feeding operation is performed.

The entire dust hood can be opened in the reverse direction. This design is beneficial for the operation of the blasting lining without disassembling the dust hood; it is convenient for the maintenance of the induction furnace gate.

During the normal shutdown and melting process, the dust removal air volume is 12 000m3/h (related to the cleanliness of the waste); when the 90 degree feed is melted, the dust removal air volume is 6 000 m3/h to 8 000 m3 /h (with the cleanliness of the waste) related).
