Device and method for cooling rail weld zone

摘要

A device for cooling a welded rail section is provided with a first cooler for cooling a head section of the welded rail section, a second cooler for cooling a column section of the welded rail section, and a control unit for controlling the first cooler and the second cooler. The first cooler is provided with a first temperature detection section for detecting the temperature of the head section, and also with a first discharge section for discharging a first cooling fluid toward the head section. The second cooler is provided with a second temperature detection section for detecting the temperature of the column section, and also with a second discharge section for discharging a second cooling fluid toward the column section. The control section individually changes the kind, amount, and flow speed of the first cooling fluid and the second cooling fluid when the head section and the column section are cooled.
