ABSTRACT:
A method and apparatus are disclosed for the continuous annealing of amorphous metal cores of the type used in electrical transformers, and wherein the cores are heated in the presence of a magnetic field. The cores are transported serially along the length of a stationary electrically conductive rod which is located within a furnace, and such that the central openings of the cores face horizontally and the rod passes through the central openings of the advancing cores. Electrical current is caused to flow through a closed loop which includes the rod so as to generate an electromagnetic field along the length of the rod and so that the cores pass through the field while being heated.
