The invention relates to an integrated frog which is an all-fiber structure and comprises a frog tip end, a frog heel end, an upper wing rail section and a lower wing rail section. The upper wing railsection is arranged between the frog tip end and the frog heel end. An integrated frog manufacturing method comprises the following steps that (1) a blank is prepared, specifically, a single-alloy ormulti-alloy electroslag steel ingot is prepared; (2) blank pressing is performed, specifically, the electroslag steel ingot is pressed into a shaped blank; (3) forging forming is performed, specifically, the shaped blank is forged and formed through a roller; (4) straightening and shaping are performed and the multi-alloy electroslag steel ingot includes at least three alloy elements. Compared with the prior art, the frog has the 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 frog is greatly improved, and an anti-fatigue life is prolonged.
本发明涉及一种一体式辙叉，所述一体式辙叉为全纤维结构，包括辙叉尖端、辙叉跟端、上翼轨段和下翼轨段，所述上翼轨段设置于辙叉尖端和辙叉跟端之间；一体式辙叉制作方法，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；（3）、锻造成型：采用轧辊将定型坯料锻造成型；（4）、校直与整形；所述多合金电渣钢锭包括至少三种合金元素。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，极大地提高了辙叉的机械性能，抗疲劳寿命提高。
