| description | Provided is method for producing a rail that can reduce bending of the rail in the height direction before correction, in the producing of ordinary rails specified in JIS E 1101. A method for producing a rail according to the present disclosure is characterized by comprising: a step for hot-rolling a slab and obtaining a rail, the slab comprising 0.60-0.85 mass% of C, 0.10-1.00 mass% of Si, 0.10-1.30 mass% of Mn, and the balance being Fe and inevitable impurities; a step for accelerating cooling of the rail under conditions in which the cooling starting temperature T1 of a rail head is 750 DEG C-850 DEG C, the cooling stopping temperature T2 of the rail head is more than 700 DEG C, and T1-T2 is 20 DEG C or more; and then a step for cooling the rail.
本发明提供一种轨道的制造方法，在JIS E 1101所规定的普通轨道的制造中，可以使矫正前的轨道的在高度方向的弯曲变小。本发明的轨道的制造方法的特征在于，具有以下工序：将具有以质量％计含有C：0.60％～0.85％、Si：0.10％～1.00％和Mn：0.10％～1.30％且剩余部分由Fe和不可避免的杂质构成的成分组成的钢片热轧而得到轨道的工序；将上述轨道在如下条件下加速冷却的工序：轨头的冷却开始温度T1：750℃～850℃、轨头的冷却停止温度T2：大于700℃、且T1-T2为20℃以上；以及，之后将上述轨道放冷的工序。 |
