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. 钢铸钢车轮制动杠杆的制备，涉及金属铸造技术领域，包括以下原料制成：合金炉料680-720kg、镍板1.0-1.4kg、高碳锰铁5-7kg。本发明的有益效果是：本发明采用加入微量合金进行浇注，形成的微合金钢铸钢制动杠杆在铁路高速运载方面，尤其是北方高寒地区，具有定
