PURPOSE:To facilitate the exchange of a refractory tube for an electromagnetic pump by securing the tube to be interposed between both side walls of a heat insulating container at the upper oblique part from the bottom of the container to a molten metal inlet, thereby using the tube as a consumable part. CONSTITUTION:An electromagnetic pump 2 is formed of a refractory tube 2a and an inductor 2b for generating a movable magnetic field, the tube 2a has two opening ends 2a1, 2a2 connected to the bottom and a molten metal inlet 3 of a heat insulating container 1, both sides are bonded to the side walls 1X1, 1X2 of the container 1, and obliquely disposed in the container 1. On the other hand, the inductor 2b is composed of a section 2b1 which is disposed along the bottom wall surface of the tube 1a and a section 2b2 which extends to the bottom of the container 1 with the length of at least one pole, and coils are continuously wound on the sections 2b1, 2b2. |
