Research on Quenching Equipment of Rail Head

摘要：

As to current problem of straightness defects and uneven quenching thickness of rail head, heating device with several induction loops are used, and through a three step strategy to realize simultaneously heating to head and bottom of rail. In air jetting phase, spray nozzles are replaced by Al alloy plates(20mm thick) with holes, adjusting to cooling strengthen can be realized by changing cross-section of holes, cooling rate is 2～4℃/sec. After the air jetting phase, there is a waterfog jetting phase, which makes 200℃ temperature gap between head and bottom of rail, to ensure quenched rail has good straightness after 48h natural aging.
