The invention relates to a switch rail which is an all-fiber structure and comprises a tip part (1) and a main body part (2). The tip part (1) and the main body part are connected into a whole body. The manufacturing method of the switch rail comprises the following steps: (1) preparing a blank: preparing a single-alloy or multi-alloy electroslag steel ingot; (2) carrying out blank pressing: pressing the electroslag steel ingot into a shaped blank, wherein a pressing temperature is 850-1250 DEG C; (3) carrying out forging forming: forging and forming the shaped blank through a roller, whereina forging temperature ranges from 850 DEG C to 1250 DEG C; and (4) straightening and shaping, wherein the multi-alloy electroslag steel ingot includes at least two alloy elements. Compared with the prior art, the switch rail has advantages that energy is saved, a material utilization rate is high, fiber structures are prevented from being damaged, a size is accurate, surface smoothness is good, mechanical performance of the switch rail is greatly improved, and an anti-fatigue life is prolonged.
本发明涉及一种尖轨，所述尖轨为全纤维结构，包括尖端部分（1）和主体部分（2），所述尖端部分（1）和所述主体部分连接成为一个整体；所述尖轨的制作方法，步骤如下：（1）、坯料制备：配置单合金或多合金电渣钢锭；（2）、坯料压制：将电渣钢锭压制成定型坯料，压制温度为850℃‑1250℃；（3）、锻造成型：采用轧辊将定型坯料锻造成型，锻造温度为850℃‑1250℃；（4）、校直与整形；所述多合金电渣钢锭包括至少两种合金元素。与现有技术相比，具有节约能源，材料利用率高，纤维组织免受破坏，尺寸准确，表面光洁度好，极大地提高了尖轨的机械性能，抗疲劳寿命提高。
