Metal melting furnace including a stirring device

A metal melt furnace including a stirring device, comprising:

• a furnace body defining a chamber for accommodating molten metal;
• the stirring device comprising a stirring rod and a drive device, a feedstock holding portion and an impeller being provided outwardly along a radial direction on an outer sidewall of the stirring rod, the drive device being in drive connection to the stirring rod so as to drive the stirring rod to rotate and lift such that the feedstock holding portion and the impeller, when being immersed in the molten metal, rotate to stir the molten metal, feedstock being held on the feedstock holding portion such that the feedstock moves along with the feedstock holding portion, wherein in a rotating direction of the stirring rod, a front end of the impeller is higher than a rear end of the impeller so as to guide the molten metal to flow from top to bottom during rotating of the impeller, and wherein the impeller is disposed below the feedstock holding portion so as to guide the molten metal carrying feedstock composition to move downward during stirring.
