| titleOfInvention | Method for preparing CT bulb tube rotor copper sleeve by combining vacuum diffusion welding with vacuum brazing |
| abstract | The invention discloses a method for preparing a CT bulb tube rotor copper sleeve by combining vacuum diffusion welding with vacuum brazing, which comprises the following steps of: s1, surface treatment: carrying out surface treatment on the carbon steel substrate and the plurality of copper conducting bars, and electroplating silver on the copper conducting bars; s2, vacuum diffusion welding: inserting the copper conducting bar into a radial fixing groove of a carbon steel substrate, and then putting the carbon steel substrate into vacuum power generation plasma equipment for vacuum diffusion welding; s3, vacuum brazing: adding brazing filler metal between the carbon steel substrate and the copper end ring after the copper conducting bar is fused for vacuum brazing at the temperature of 900-950 ℃ to obtain a workpiece; s4, heat treatment: continuously placing the workpiece subjected to vacuum brazing in a vacuum brazing furnace for heat treatment; and S5, precision machining. The invention combines vacuum diffusion welding and vacuum brazing to prepare the rotor copper sleeve meeting the high-temperature vacuum use environment of the CT bulb tube, and can meet the special requirements of the CT bulb tube industry. |
