Novel railhead profile steel rail and production method thereof
The invention discloses a novel railhead profile steel rail and a production method thereof. The novel railhead profile steel rail is composed of a steel rail base and a top outline. Specifically, thesteel rail base is a 60 steel rail base, the top outline is of a bilateral symmetry structure and is provided with seven sections of arcs, the radius of a middle arc is 200mm, and the radiuses of thearcs in the direction from the middle to the two sides are 60mm, 16mm and 8mm respectively. According to the novel railhead profile steel rail, wheel-rail profile matching can be achieved, thereforethe service life of the steel rail is prolonged.
本发明公开了一种新轨头廓形钢轨及其生产方法，提供的新轨头廓形钢轨由钢轨基座和顶部轮廓构成，其中所述钢轨基座为60钢轨基座，所述顶部轮廓为左右对称结构，具备七段圆弧，其中中间圆弧的半径为200mm，从中间向两边方向上的圆弧的半径分别为60mm、16mm和8mm。提供的新轨头廓形钢轨可以实现轮轨形面匹配，从而延长钢轨的使用寿命。
