Research on Contact Fatigue of Locomotive Wheel Treads
The traditional CL60 material freight wheels can not meet the current development needs of heavy haul railway freight transportation.The Academy of Railway Sciences has timely developed CL65 and CL70 heavy haul wheel steels with silicon and manganese as strengthening elements.However,the application of new material also brings some difficulties to wheel production.Based on the actual production,this paper analyses the difficulties of billet smelting,rolling,heat treatment and processing,and optimizes the process to ensure product quality.
