Vacuum induction furnace capable of smelting aluminum and aluminum alloy

Abstract

The invention discloses a vacuum induction furnace capable of smelting aluminum and aluminum alloy. The vacuum induction furnace comprises a furnace body erected at the top of a furnace frame, a liftable furnace bottom plate arranged at the bottom end of the furnace body and bearing a graphite crucible, an induction coil arranged in the furnace body, an air suction pipe arranged on the side wall of the furnace body, a charging pipe penetrating through a furnace cover, a stirring shaft penetrating through the furnace cover, a stirring frame arranged at the bottom of the stirring shaft, a through hole formed in the stirring shaft, an argon blowing pipe penetrating through the through hole and extending to the bottom of an inner cavity of the graphite crucible, an argon supply device connected with the argon blowing pipe, a trolley arranged under the furnace body and capable of bearing the furnace bottom plate, and a lifting driving mechanism used for driving the furnace bottom plate to rise and fall vertically. The graphite crucible of the vacuum induction furnace is borne by the liftable furnace bottom plate, thereby entering and going out of the furnace body conveniently. The furnace bottom plate and the graphite crucible can be transported by the trolley, and moving is convenient. The stirring mechanism can conduct stirring during smelting of the aluminum and the aluminum alloy, argon can be led into aluminum liquid during stirring, and a purification effect can be achieved.

Description

technical field [0001] The invention relates to a vacuum induction furnace capable of smelting aluminum and its alloys. Background technique [0002] Vacuum induction furnaces can be used for smelting aluminum and its alloys, but the existing vacuum induction furnaces are very troublesome for loading and unloading materials. The aluminum material is placed in the crucible. After the heating process, the crucible needs to be lifted out of the induction furnace by a crane. Then put the raw materials into the crucible and then hoist them into the induction furnace, which requires a lot of manpower and material resources. When picking up the materials, it needs to cool down and then start the hoist, which also wastes a lot of man-hours. Contents of the invention [0003] The object of the present invention is to provide a vacuum induction furnace capable of smelting aluminum and its alloys. The graphite crucible is carried by a liftable furnace floor, which is convenient for e...
