Abstract
In a method for producing fine wire, a wire blank is transformed by a heat treatment process into a drawable state, the wire blank is drawn to a drawn wire, and, subsequently, the drawn wire is subjected, to a hardening and tempering process in order to obtain predetermined mechanical properties by passing the drawn wire through at least one of a furnace device and a cooling device having previously already been employed for performing the heat treatment process. The furnace device has a furnace chamber, receiving at least one wire portion, with a heat distribution block arranged in the area where the wire portion is received. The heat distribution block is designed to uniformly heat the wire portion. The cooling device has a fluidized chamber containing a flowable material. A fluid introduction arrangement is provided to introduce a fluidizing fluid into the fluidized chamber. A heating arrangement is provided for heating the flowable material, wherein the heating arrangement emits electromagnetic waves into the fluidized chamber.
