Abstract
The invention discloses a manufacturing technology for a methanation furnace body end socket. The technology includes the processes of steel plate reinspection, pretreating, discharging, edge machining, butt welding line assembling, welding, heating, pressing and secondary cutting. Shot blasting and paint spraying are adopted in the surface pretreating. The combination of shielded metal arc welding and union melt welding is adopted at end socket butt lines. A numerical control cutting machine is used in edge machining for conducting groove machining, the allowance of 10 mm is reserved in groove machining, and then a mechanical device is used for polishing the periphery of a groove. The method for pressing after heating is used for pressing the end socket, the heating temperature is 980 DEG C, secondary line marking is conducted after pressing forming, and secondary cutting is conducted by means of a welding rotation table. Equipment is simple, cost is low, the production efficiency is high, mechanization and automation are easy to achieve, the cutting quality is good, and the limitation of shapes and sizes of workpieces does not exist.
