摘要: A rail restraining method for restraining a hot-rolled rail in an upright position at a time of forced cooling of a head portion and a foot portion of the rail includes defining a predetermined position within 2 meters from each of both end faces of the rail along a longitudinal direction of the rail as a first restraining position, defining a predetermined position 3 to 10 meters from the first restraining position in a direction toward center of the rail along the longitudinal direction of the rail as a second restraining position at the time of forced cooling, and restraining displacement of the rail in a vertical direction at the first restraining position and the second restraining position by a restraining force F (kN) that satisfies following Expression (1): F≧100/L2 (1) where L2 (m) is a distance between the first restraining position and the second restraining position.

摘要: A rail cooling method includes: calculating, based on a relation between temperatures and an amount of warp of the rail cooled to ambient temperature after the forced cooling, the temperatures including a cooling start temperature of the head, a cooling end temperature of the head, a cooling start temperature of the foot and a cooling end temperature of the foot, a target value or a target value range for each of the temperatures so that the amount of warp of the rail at ambient temperature falls within a permissive range; and setting a cooling condition in accordance with the target value or the target value range to perform the forced cooling on the head and the foot.
