    摘要: A device for cooling a rail weld zone according to the invention includes a first cooler cooling a head portion of the rail weld zone, a second cooler cooling a rail web portion of the rail weld zone, and a control section controlling the first and second coolers. The first cooler includes a first temperature detecting section that detects the temperature of the head portion, and a first ejection section that ejects a first cooling fluid to the head portion. The second cooler includes a second temperature detecting section that detects the temperature of the rail web portion, and a second ejection section that ejects a second cooling fluid to the rail web portion. The control section individually changes the kinds, the flow rates, and the flow velocities of the first and second cooling fluids while cooling the head portion and the rail web portion.

    摘要: The invention provides a method of cooling a rail weld zone. The method includes a first rail web portion cooling process of cooling a rail web portion cooling region of the rail weld zone in a part of a temperature range until the completion of transformation from austenite to pearlite, a second rail web portion cooling process of cooling the rail web portion cooling region after the entire rail web portion of the rail weld zone is transformed to pearlite, a foot portion cooling process of cooling a foot portion of the rail weld zone, and a head portion cooling process of cooling a head portion of the rail weld zone. When cooling time of the first and second rail web portion cooling processes is t minute, a k value satisfies an expression represented as -0.1t+0.63≤k≤-0.1t+2.33.
