Summary: | The invention provides preparation of a steel casting steel wheel braking lever, and relates to the technical field of metal casting, wherein the steel casting steel wheel braking lever is prepared from the following raw materials: 680-720 kg of an alloy furnace material, 1.0-1.4 kg of a nickel plate, and 5-7 kg of high-carbon ferromanganese. According to the present invention, the trace alloy isadded to perform casting, such that the formed micro-alloy steel casting steel braking lever has a certain advantage in the high-speed railway transportation, especially in the northern high-cold regions, wherein the strength and the hardness of the micro-alloy steel casting steel braking lever are comparable to the strength and the hardness of the class-B steel braking lever while the cost of themicro-alloy steel casting steel braking lever is about 2/3 of the cost of the class-B steels.
