[0036] Furthermore, the grinding part includes a telescopic connection port opened on the side wall of the pretreatment port 6, the inner wall of the telescopic connection port is connected to the bevel limit block 7 through a reset spring, an insertion port penetrating the side wall is opened at the top of the telescopic connection port, the side wall of the bevel limit block 7 is fixedly connected with a grinding strip 34 extending into the pretreatment port 6, and a plug-in bevel block 21 adapted to the bevel limit block 7 is provided at the bottom of the pressure plate 19.

[0037] A further advantage of adopting the above method is that when the pressure plate 19 moves downward, the plug-in ramp block 21 provided thereon will be inserted downward into the plug-in port. When the plug-in ramp block 21 moves downward, the ramp limit block 7 will be squeezed to drive the grinding strips 34 located on both sides to move gradually inward, thereby grinding and feeding the surface of the rotating magnesium ingot, thereby removing the oxide layer.

[0038] An outer protective cover body 8 is fixedly arranged above the auxiliary heating ring seat 2, and a driving rotary member for driving the rotating extrusion member is arranged inside the outer protective cover body 8.

[0039] Furthermore, the blocking stirring element includes a stirring shaft 9 that is detachably connected to the stirring motor, a plurality of stirring blades are arranged on the stirring shaft 9, and a plurality of inner protective isolation blades 10 are arranged on the inner wall of the smelting furnace body 1, and the inner protective isolation blades 10 are connected to the stirring shaft 9 through connecting columns.

[0040] The inner protective isolation leaf 10 fits tightly against the inner wall of the smelting furnace body 1, and during its rotation, it will open and close the cylindrical punching port 11 opened on the inner wall of the smelting furnace body 1. When the inner protective isolation leaf 10 closes the cylindrical punching port 11, the hydraulic push rod 12 will pressurize the magnesium melt in the cylindrical punching port 11. When the inner protective isolation leaf 10 opens the cylindrical punching port 11, the pressurized magnesium melt is sprayed at high speed into the stirred alloy smelting melt for rapid mixing, thereby improving the fusion efficiency and preventing the magnesium melt from being oxidized when it contacts the air.

[0041] Furthermore, the high-pressure punching assembly includes a cylindrical punching port 11 opened at the bottom of the auxiliary heating chamber 3 and penetrating the side wall of the smelting furnace body 1.

[0044] A rotating extrusion member is provided in the pretreatment port 6, and the rotating extrusion member includes an extrusion cone disk 23 fixedly provided on both sides of the pretreatment port 6, the extrusion cone disk 23 located on the inner side is fixedly connected to the inner wall of the pretreatment port 6, and the extrusion cone disk 23 located on the outer side is fixedly connected to an extrusion drum 24, and the extrusion drum 24 is slidably connected to a rotation shaft 25 through a key groove member;

[0045] Furthermore, a magnetic repulsion arc plate 26 is provided on the inner wall of the outer shield body 8 , and the extrusion drum 24 is provided through the inner wall of the pretreatment port 6 , and a magnetic repulsion disk 27 that magnetically repels the magnetic repulsion arc plate 26 is provided at its end.

[0046] The advantage of adopting the above structure is that when the pretreatment ring seat 5 rotates, the magnetic repulsion disk 27 that was originally misaligned with the magnetic repulsion arc plate 26 will rotate to the corresponding angle of the magnetic repulsion arc plate 26. At this time, the magnetic repulsion disk 27 will be driven by the pressure of the magnetic repulsion force to drive the extrusion drum 24 to move inward, so that the extrusion cone disk 23 connected to it can clamp the end of the magnesium ingot in the pretreatment port 6, thereby ensuring that the magnesium ingot can be driven to rotate by the rotating extrusion piece.

[0048] The driving motor 30 drives the driving gear 31 at its output end, and the driving gear 31 drives the rotating gear ring 29 to rotate. The rotation of the rotating gear ring 29 drives the rotating shaft 25 to rotate, thereby rotating the extrusion cone 23 and realizing the rotation of the magnesium ingot.

[0049] When the present invention is used, the mass ratio is calculated according to the ratio of the aluminum-magnesium alloy, the mass ratio of the corresponding metal is weighed, and the magnesium metal column is taken out separately and placed in the pretreatment port 6, and the remaining metal is placed in the smelting furnace for centralized smelting;

[0050] The magnesium metal column placed in the pretreatment port 6 is ground to remove the magnesium oxide layer on the surface of the magnesium metal column, and the ground powder is collected and weighed through the grinding debris collection port 14 set on the isolation annular plate 4, and the weighed magnesium metal is compensated and added;

[0051] The ground magnesium metal column is cut into slices by the slicing blade at the bottom of the cutting block 22. Under the action of gravity, the cut magnesium metal column falls into the auxiliary heating chamber 3 and is heated and melted into magnesium melt by the resistive heating element arranged in the auxiliary heating chamber 3.

[0052] The alloy metal being smelted in the smelting furnace is stirred by the blocking stirring member; during the stirring process, the hydraulic push rod 12 drives the stamping isolation plate 13 to extrude the smelted magnesium melt to increase the pressure, and under the action of the pressure, the magnesium melt is impacted into the smelting furnace at a high speed for sufficient mixing.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
