Extreme Manufacturing Technology of Profiling Transition Section of Large Hydrogenation Reactor
The shape characteristics of the lower transition section of the hydrogenation reaction pressure vessel are analyzed,different forming schemes are compared,and the profiling forging method is selected for production. The corresponding solutions are taken to solve the problems faced by the whole manufacturing process,such as smelting,forging and heat treatment. Through the strict screening of raw materials,the argon soft blowing time is extended,so that the deoxidation products such as Al2O3 can float upward completely. In view of the size of the existing reaming assistive device and the shortage of clearance of hydraulic press,the extreme forging is carried out by adding new high pad,machining and reusing the abandoned assistive device,and controlling the size during the forging process. Through reasonable heat treatment process and internal control of chemical elements,the performance of forging is improved,and the manufacturing technology of the lower transition section of hydrogenation reaction pressure vessel is proved to be reasonable and feasible.
