Molten Metal Stirring Device

摘要

A stirring device for molten metals such as aluminum. The device involves a mechanism which inserts and dips a nozzle-shaped stirring tube into a melting furnace through an insertion hole opened in the side wall of the furnace and stirs the molten metal using the stirring tube to repeatedly suck up and blow down the molten metal. The first claimed mechanism consists of the insertion hole opened through the side wall at an angle and an external unit having a tilting and inserting mechanism to tilt the stirring tube and insert it into the insertion hole. The second claimed mechanism consists of a transportable structure which has a transferrable base provided with a support frame to mount the stirring tube connected to the tilting mechanism, a positioning mechanism to allow axial movement of the stirring tube, and other necessary operating units.
