[0001] The utility model relates to the technical field of alloy smelting, in particular to a vertical magnesium alloy smelting furnace. Background Art

[0002] The application of magnesium and magnesium alloys in industry is greatly limited due to their low strength, low hardness and poor corrosion resistance. In order to improve the mechanical properties of magnesium and magnesium alloys, rare earth elements and reinforcing materials are often doped during the smelting process of magnesium alloys. However, the smelting equipment currently used is mostly backward and cannot flexibly adjust the smelting space according to the capacity of the magnesium alloy, resulting in high smelting energy consumption.

[0003] However, in the prior art, for example, China Publication No.: CN20844318U, "A vertical melting furnace for smelting aluminum-magnesium alloys", the utility model discloses a vertical melting furnace for smelting aluminum-magnesium alloys, including a furnace body, a fixed cylinder is provided inside the furnace body, and an array of connecting columns is distributed on the lower surface of the fixed cylinder, and the connecting columns are fixedly connected to the inner upper surface of the furnace body, and a heating coil is distributed in an array on the upper and lower surfaces of the outer surface of the fixed cylinder, and the heating coil is fixedly connected to the outer side surface of the fixed cylinder through a conductive fixing plate, a crucible furnace is provided inside the fixed cylinder, and a second fixing ring is provided on the upper surface of the crucible furnace, and two handles are provided on the upper surface of the second fixing ring correspondingly arranged front and back, and a water pump is provided on the front side of the furnace body.
