ALUMINUM MELTING FURNACE WITH STIRRING DEVICE, MOLTEN ALUMINUM STIRRING DEVICE AND METHOD FOR STIRRING MOLTEN ALUMINUM

摘要

PROBLEM TO BE SOLVED: To reduce the manufacturing cost and the running cost of an aluminum melting furnace with a stirring device. ;SOLUTION: A burner 4 is arranged at the upper part of a furnace body 20 for storing the molten aluminum 22, and a disk-like magnet base 31 fitting a permanent magnet 32 is arranged near the furnace body 20, e.g. at the lower part of the bottom part 20a. Magnetic field generated with the permanent magnet 32 is rotated by rotating the magnet base 31 with a motor 43 to stir the molten aluminum 22. By this method, a cooling device for electromagnetic coil needed in the conventional device is unnecessitated and also, the consumption of electric power is restrained.;COPYRIGHT: (C)1998,JPO
