Method and arrangement for inhomogeneous annealing of small parts

摘要

An arrangement for providing controlled annealing of parts within a furnace comprising a series of heat radiation distributors, thermal conduction dosing devices and heat accumulators positioned within the furnace to provide a temperature gradient in the radial direction of the furnace cross section. The controlled temperature distribution within the furnace provides a controlled temperature distribution to the objects within the furnace during the annealing process. This controlled annealing process is particularly applicable to a method for controlling the coercive force distribution within a magnetically hard reed armature for matching the coercive force distribution along the armature to the magnetic flux intensity of the reed contact assembly.
