Abstract

The disclosure discloses a magnesium alloy material smelting device, comprising a furnace, a disc packing device, the disc packing device comprising a stirring shaft, a packing basket, a disc stirring head, the stirring shaft connected with a packing basket, the bottom of the packing basket connected with a disc stirring head, the disc stirring head comprising a plurality of stirring wings, the stirring wings connected with the packing basket and the stirring disc, the connecting ends of the stirring wings connected with each other, the stirring ends extending to the edge of the stirring disc, and the sidewall of the packing basket provided with a liquid passage hole; during the process of preparing and processing the magnesium alloy, the disc stirring head may accelerate the diffusion, the rotation of the disc stirring head may divide the melt into upper and lower layers, and the upper layer of the melt forms a solution vortex to accelerate the diffusion of the master alloy elements; the lower melt keeps relatively static to avoid the upturn of precipitated slag and shorten the precipitation time of slag, thereby improving the productivity.

First claim

What is claimed is:

1. A magnesium alloy material smelting device, comprising a furnace, a disc packing device, wherein the disc packing device comprises a stirring shaft, a packing basket, a disc stirring head, the stirring shaft connected with the packing basket, the bottom of the packing basket connected with the disc stirring head, the disc stirring head comprising a plurality of stirring wings, the stirring wings connected with the packing basket and the stirring disc, connecting ends of the stirring wings connected with each other, stirring ends of the stirring wings extending to an edge of the stirring disc to stir magnesium alloy solution, and a side wall of the packing basket provided with a liquid passage hole to exchange liquid with the solution outside the packing basket,
wherein the stirring wings are of right-angle trapezoidal structure with a bevel edge of concave arc shape.

2. A magnesium alloy material smelting device according to claim 1 , wherein respective surfaces of the stirring wings from the connecting end to the stirring end are arc-shaped, and an included angle between a tangential direction of the stirring end and a tangential direction of the stirring disc at the corresponding position is θ.

3. A magnesium alloy material smelting device according to claim 2 , wherein the included angle θ is 30°-45°.

4. A magnesium alloy material smelting device according to claim 3 , wherein the number of stirring wings is four, and each adjacent stirring wing is vertically connected with each other.

5. A magnesium alloy material smelting device according to claim 1 , wherein the stirring disc is disc-shaped and has a diameter 2-3 times that of the packing basket.

6. A magnesium alloy material smelting device according to claim 1 , wherein the disc packing device further comprises partition plates dividing the packing basket into a plurality of packing bins.

7. A magnesium alloy material smelting device according to claim 6 , wherein the partition plates are uniformly arranged in four, and the packing basket is divided into four packing bins.

8. A magnesium alloy material smelting device according to claim 1 , wherein the bottom of the packing basket is also uniformly provided with liquid passage holes.

9. A magnesium alloy material smelting device according to claim 1 , wherein the disc packing device is made of iron and steel material.
