现在有一种热处理新加热方法,可以取代现有的各种加热方法。即:将直流电直接通入热处理件。在数秒钟之内使其达到奥氏体化温度。采用这种方法加热的碳钢和合金钢,可以用水淬火。其金相组织细致均匀,机械强度和其他机械性能均超过现有各种加热方法。热处理后不需要重新校直、内应 There is now a heat treatment of new heating methods that can replace the existing variety of heating methods. Namely: the direct current into the heat treatment pieces. In a few seconds to reach the austenitizing temperature. Carbon steel and alloy steels heated in this way can be quenched with water. The metallurgical structure of meticulous uniform, mechanical strength and other mechanical properties than the existing variety of heating methods. After the heat treatment does not require re-alignment, the internal should
