The electromagnetic stirrer 12 needs to be connected to the electric control system, and a combined alternating magnetic field is applied by the electric control system to achieve vertical rotation of the molten metal, thereby achieving the purpose of stirring the metal liquid, which will not be elaborated here.

[0025] like Figure 2 , Figure 3 and Figure 4 as well as Figure 5As shown, the wall surface of the base 10 is provided with an adjustment component for driving the displacement of the electromagnetic stirrer 12, and the adjustment component can push the electromagnetic stirrer 12 to vertically displace and revolve around the crucible furnace body 11. The adjustment component includes a load-bearing plate 20, a vertical plate 21, a screw rod 22, a limit rod 23 and a connecting plate 24. The load-bearing plate 20 is slidably connected to the base 10, the vertical plate 21 is fixedly connected to the load-bearing plate 20, the screw rod 22 is rotatably connected to the vertical plate 21, the limit rod 23 is fixedly connected to the vertical plate 21, and the connecting plate 24 is fixedly connected to the load-bearing plate 20. The electromagnetic stirrer 12 is fixedly installed on the top of the connecting plate 24, and the screw rod 22 can push the connecting plate 24 to slide radially along the limit rod 23. A motor is provided on the top of the base 10 to drive the load-bearing plate 20 to rotate, and the load-bearing plate 20 forms an annular structure. A plurality of balls are provided on the bottom surface of the load-bearing plate 20, and the balls are rotatably connected to the load-bearing plate 20. An annular slide rail is provided on the top surface of the base 10, and the slide rail is provided with a slideway. The motor is fixedly mounted on the top of the base 10, and the motor output shaft is fixedly connected with a gear. In this scheme, compared with the stirring method on the horizontally arranged electromagnetic stirring seat used in the prior art, the electromagnetic stirrer 12 is vertically arranged on the outside of the crucible furnace body 11, and the metal liquid in the crucible furnace body 11 flows from the middle position to the two sides through the electromagnetic stirrer 12, thereby promoting the mutual extrusion convection effect of the inner wall and the center position of the crucible furnace body 11, ensuring the uniformity of the mixing of the metal liquid, and having higher efficiency. The connecting plate 24 is pushed by the screw rod 22 to slide along the limit rod 23, and the connecting plate 24 drives the electromagnetic stirrer 12 to move vertically. At the same time, the load-bearing plate 20 is driven by the motor on the top surface of the base 10 to rotate horizontally, so as to realize the horizontal and vertical movement of the electromagnetic stirrer 12, and the stirring position is constantly changed, so as to further improve the mixing effect of the liquid in the crucible furnace body 11 cavity, and help promote actual production.
