摘　　要：采用激光淬火工艺加工的车轮轮对踏面,车轮受热变形很小,热处理后的车轮不需要后续机械加工就可以满足实际工况的需求,不仅可以有效地延长轮对的使用寿命和降低维护费用,还可以显著提高轮对抵抗钢轨冲击和耐摩擦的能力。Laser quenching technology will be applied to wheel tread processing.Thermal deformation of the wheel is small,the wheels do not heat up after machining to meet the needs of the actual working conditions,which can not only effectively extend the wheel life and reduce maintenance costs,but also can significantly improve the impact and wheel rubbing against the ability of the rail.
