闸述了重型钢轨轨端热处理的重要性,介绍了正交试验方法在确定重轨轨端热处理工艺参数中的作用,评价了气、水二相冷却剂在轨端淬火中的应用效果,并对这种冷却剂的配制作了较详细的说明。
The importance of heat treatment of heavy rail ends was introduced. The effect of orthogonal test method in determining heat treatment process parameters of heavy rail ends was introduced. The effect of gas and water two phase coolant on rail end quenching was evaluated. The preparation of such a coolant is described in more detail.
