摘要: A heat-treating apparatus comprises zones such as a carburizing zone, a cooling zone, and a nitriding zone, those zones are formed in series by partitioning a continuous passage through doors, and conveyance means for conveying an object along the passage. The cooling zone comprises a forced-feed cooling means for cooling the object by blowing cooling gas.
