Abstract
A furnace for the heat treatment of wire materials, comprising a cylindrical furnace body having holes at both ends through which a wire material is inserted into and out of the furnace body, a combustion chamber formed within the furnace body, a burner provided at one end portion of the furnace body and adjacent to the combustion chamber, and a discharge pipe mounted near the downstream edge of the combustion chamber for discharging the waste gas. The burner comprises a free space through which the wire material is inserted, a fuel-air mixture chamber surrounding the free space, and injection nozzles communicating with the fuel-air mixture chamber and serving to inject the mixture into the combustion chamber. The injection nozzles are arranged to permit the injected streams of fuel-air mixture to make whirling motions in the same direction along the inner wall of the combustion chamber in such a manner as to be free from direct contact with the wire material running along the axis of the combustion chamber.
