Research on High-precision Bainitic Rocket Jack Slideway Weld Seam Induction Normalizing Technology
In order to solve the problem of defect echoes appearing in the welded joint of the rail head of the Bainite steel rail during the induction annealing process,the welded joint of the rail head was analyzed by ultrasonic testing data,and the induction heating power and heating time of the heat treatment equipment were improved to form the flash welding annealing technology of Bainite steel rail.The experimental verification was carried out on the difficult parts to meet the inspection requirements during the inspection,the results show that the annealing technology solves the inspection requirements of the Bainite steel rail welded joint,and meets the experimental use demand of the ultra-high precision rocket lever sliding rail.
