The invention discloses a high-density turnout steel rail and a production method thereof. The method comprises the steps of adopting a high-purity steel smelting process for smelting a steel billet; after the steel billet is cooled and heated again, heating the steel billet; and adopting a rolling process that the quotient of the average height of the steel billet and the diameter of a roller is 0.1-0.5, and rolling the steel billet into the turnout steel rail, wherein the rolling compression ratio is larger than or equal to 12:1. By adopting the production method of the high-density turnout steel rail, the high-density turnout steel rail with the low alarm rate and high purity can be obtained.
本发明公开了一种高致密度道岔钢轨及其生产方法，该方法包括：采用高纯净钢冶炼工艺冶炼钢坯。在所述钢坯经冷却再次加热之后，对所述钢坯进行加热。采用钢坯平均高度与轧辊直径之商在0.1‑0.5之间的轧制工艺，将所述钢坯轧制成道岔钢轨，所述轧制压缩比大于等于12:1。本发明采用高致密度道岔钢轨生产方法能够得到低报警率、高纯净度的高致密度道岔钢轨。
