JX-Ⅰ型缓冲装置用在铁路车钩上,其工作条件为机车与车辆之间牵引和缓冲。其中的构尾框及从板采用E级高强度合金钢铸造,此装置系引进NC-391型缓冲装置技术国内生产的产品,对强度和韧性指标要求较高。为保证达到钢铸件技术条件规范（AAR—M201）的要求,我们对此种钢的热处理工艺进行了研究,在多次试验的基础上制定了一套最佳热处理方案,使其成品的各项性能指标达到甚至超过了同类进口产品的指标。 考虑到总公司系统有的单位要进行铁路临管,将会遇到加工此类部件的问题,故将我们对构尾框热处理工艺的研究试验情况介绍于下,供届时参考。
JX-Ⅰ-type buffer device used in the railway car hook, the working conditions for traction and buffering between the locomotive and the vehicle. One of the tail frame and the plate from the E-class high-strength alloy steel casting, this device is the introduction of NC-391-type buffer device technology products domestically produced, on the strength and toughness of the higher requirements. In order to meet the requirements of AAR-M201, we have studied the heat treatment process of this kind of steel. On the basis of many experiments, we have developed a set of optimal heat treatment plan to make all the finished products Performance indicators meet or exceed the same type of imported products indicators. Taking into account the head office system of some units to be on-line railway, will encounter the processing of such components, it will be our end frame heat treatment process research and experimental conditions introduced below, for reference.
