摘要： A continuous gas carburizing furnace includes a gas carburizing processing, chamber (a preheating chamber (2), a heating chamber (3), a carburizing chamber (4), a diffusion chamber (5) and a temperature decrease chamber (6) in which a gas carburizing process is performed on a workpiece (50), an oil quenching chamber (8) in which oil quenching is performed on the (workpiece 50), and a gas quenching chamber (7) in which gas quenching is performed on the workpiece (50). The gas carburizing processing chamber includes a temperature decrease chamber (6) in which the temperature of the workpiece heated by a gas carburizing process is lowered. The temperature decrease chamber (6), the gas quenching chamber (7) and the oil quenching chamber (8) are arranged in that order from the upstream side to the downstream side in the conveying direction of the workpiece (50), and are adjacent to each other.
