The project features 3 suspended-bed reactors, which are made of special materials and have an extremely thick structure; each reactor weighs 1,830 tons. The main body of each reactor is manufactured in three sections at the Qingdao factory, after which it is transported to Panjin Haoye for final assembly, welding of the circumferential seams, and heat treatment. For the 6 circumferential seams involved in the final assembly, a completely new electromagnetic induction heating technique is used for heat treatment after welding. The heat treatment project team for the hydrogenation reactor at Panjin Haoye, affiliated with the Qingdao company, worked in close collaboration with Lanshi Heavy Equipment’s mobile factory, working day and night to overcome various challenges associated with the practical application of new electromagnetic induction heating technologies. On March 10, the post-weld heat treatment for the local area of the first assembly ring seam was successfully completed, providing a comprehensive evaluation of the electromagnetic induction heating technology and its implementation plan.
