Method and apparatus for producing fine wire

An apparatus for performing a method for producing fine wire including the steps of:

• transforming a wire blank by a heat treatment process into a drawable state;
• drawing the wire blank to a drawn wire;
• and
• subsequently subjecting the drawn wire 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 apparatus comprising at least one furnace device with at least one heatable furnace chamber configured to receive at least one wire portion of the wire blank or the drawn wire, wherein the furnace chamber comprises a heat distribution block arranged in the area where the wire portion is to be received, wherein the heat distribution block is configured to uniformly heat the wire portion;
• and
• a cooling device comprising:
• a fluidized chamber containing a flowable material;
• a fluid introduction arrangement configured to introduce a fluidizing fluid into the fluidized chamber;
• and a heating arrangement configured to heat the flowable material, wherein the heating arrangement is configured to emit electromagnetic waves into the fluidized chamber.
