ABSTRACT:
A combination sintering-annealing furnace is provided, wherein the sintering furnace section and the annealing furnace section are arranged adjacent with each other and separated by a partition wall. A plurality of ventilation windows is provided through the partition wall to allow the waste combustion gas in the sintering furnace to flow into the annealing furnace. The opening area of each ventilation window is adjusted by an adjuster plate. The annealing furnace is also provided with a plurality of cold air inlet ports for introducing therethrough cold air from the atmosphere, the opening area of each cold air inlet port being adjusted by an adjuster plate. A desired temperature distribution in the annealing furnace may be established by controlling the opening areas of the respective ventilation windows and respective cold air inlet ports.
