摘要： A heat treatment furnace is sub-divided by an internal wall into an ante-chamber and a treatment chamber arranged so that workpieces pass through an entry of the furnace into the antechamber, and thence through the treatment chamber to an exit of the furnace. Fuel-fired heating tubes are provided in the treatment chamber to radiate heat to workpieces therein and the tubes are arranged to discharge into the ante-chamber so that the hot products of combustion contact the workpieces in the antechamber. The ante-chamber itself is sub-divided into front and rear parts, and the front part is provided with a gas outlet through which the products of combustion from the heating tubes can leave the furnace. Air may be drawn through the entry into the front part of the ante-chamber to burn off oil from the workpieces therein.
