The invention discloses a medium-strength steel rail and a production method thereof. The method comprises the following steps: smelting and casting a steel billet with the cross section area being greater than or equal to 1000 mm <2> by adopting a high-purity steel smelting process, heating the steel billet, and rolling the steel billet into a steel rail, wherein the length of the steel rail is greater than or equal to 75 cm, the piece weight is less than or equal to 60 kg/m, and the cross section area is 57-78 mm <2>. By adopting the medium-strength steel rail production method, the medium-strength steel rail with low cost and high performance can be obtained.
本发明公开了一种中等强度钢轨及其生产方法，该方法包括：采用高纯净钢冶炼工艺冶炼浇铸截面面积≥1000mm2的钢坯，对所述钢坯进行加热，将所述钢坯轧制成钢轨，所述钢轨的长度≥75cm，单重≤60kg/m，截面面积在57‑78mm2。本发明采用中等强度钢轨生产方法能够得到低成本、高性能的中等强度钢轨。
