[0002] Nowadays, with the continuous development of industry, electric furnaces have been widely used in various fields as a common heating equipment. During the heating process, the generation of oxides is an inevitable problem. This will lead to the reduction of material quality and performance, thus affecting the use effect of the product. Therefore, it is very important to seal and evacuate the electric furnace. When heating, the mobile electric furnace needs to evacuate the interior to remove oxides. At high temperatures, oxides in metals or alloys are easily generated and will reduce the quality and performance of the materials. By evacuating, oxygen, nitrogen and other gases in the furnace can be removed to avoid reaction with elements in the material, thereby reducing the possibility of oxide generation and avoiding air pollution. However, the existing equipment cannot effectively seal the connecting equipment in one direction when evacuating, which can easily cause air backflow, thereby causing internal pollution, and the existing sealing mechanism is not tight enough.
