Abstract
This invention is directed to a method for annealing strand wires or strips in a fluidized bed reactor having an atmosphere of fluidized gases flowing through fluidized particles. The method provides for stratifying the atmosphere of fluidized gases by passing a reducing gas through the fluidized particles in the fluidized bed. The wires are passed between the fluidized particles at a location near the bottom of the fluidized bed. Finally, an amount of oxygen-containing gas is injected on top of said fluidized bed reactor.
