Combined frog point rail and preparation method thereof
The invention provides a combined frog point rail and a preparation method thereof. The combined frog point rail is composed of a point rail A and point rail spacer iron B which are integrally formed. The integrally formed combined frog point rail is a combined frog point rail manufactured by adopting an I-shaped point rail blank C with a uniform section; the preparation method comprises the steps of determining steel types; the rolling or forging ratio is determined according to the frog model; manufacturing an I-shaped point rail blank C by adopting a continuous casting, continuous rolling or forging and die forging process mode; selecting a proper heat treatment process according to the steel grade to perform heat treatment on the I-shaped point rail blank C; and processing and forming. The technical problems that an existing point rail and a point rail preparation method are large in machining range, low in material utilization rate, high in manufacturing cost, poor in process quality stability, low in operability and inconvenient to popularize in the market are solved. According to the invention, the requirements of factory batch production can be met, the manufacturing cost is relatively low, and the popularization value is relatively high.
提供一种组合辙叉心轨及其制备方法，组合辙叉心轨由一体成型的心轨A与心轨间隔铁B组成；且一体成型的组合辙叉心轨为采用等截面的工字型心轨毛坯C制造而成的组合辙叉心轨；制备方法包括确定钢种；根据辙叉型号确定轧制或锻造比；采用连铸、连轧或锻造、模锻工艺方式制作工字型心轨毛坯C；根据钢种选择适宜的热处理工艺对所述工字型心轨毛坯C进行热处理；加工成型。本发明解决现有心轨及心轨制备方法加工范围较大，材料利用率低，制造成本高，工艺质量稳定性不佳，可操作性不高，不便市场推广普及的技术问题；本发明能够满足工厂批量化生产要求，制造成本相对较低，具有较高的推广价值。
