PURPOSE: An impeller for stirring molten iron is provided to extend the service life of the impeller by preventing cracks due to thermal stress and erosion due to the molten iron. CONSTITUTION: An impeller(100) for stirring molten iron comprises a body(110), multiple wings(120), and one or more cooling water passages. Part of the body is dipped in molten iron, and one side of the body is rotatably connected to the outside. The body is made of metal or a metal alloy material. The wings are formed of the metal or the metal alloy material, and raidally protrude along the exterior of the body. The cooling water passages are formed inside the body and the wings to pass through cooling water. [Reference numerals] (138) Control unit; |
