Abstract: A core-inlaid high manganese steel frog structure includes a high manganese steel frog body and an inlaid core. The high manganese steel frog body includes a swing track connecting section, a frog central section and a frog-and-track connecting section. The wing track connecting section and the frog-and-track connecting section are respectively arranged on front and rear ends of the frog central section. A mounting groove for cooperatively mounting the inlaid core is arranged in front of the frog central section. The high manganese steel frog body and the inlaid core are detachably connected. The high manganese steel frog body and the inlaid core are detachably connected, which facilitates replacement of vulnerable parts, saves cost, and meets user requirements. The material and production procedure for the high-manganese steel frog body can be different from those for the inlaid core, which helps further improve the performance of the inlaid core.
