The steel ring is made of hot-rolled steel, and the steel ring is made of plate and band steel. The manufacturing process is also different, and the section steel ring is as follows: blanking, rolling, pressing, double cutting, flattening, butt welding, scraping, rounding, polishing, expanding, shrinking, punching a valve hole and lathing an inner hole. The steel ring of the plate is as follows: blanking, typewriting, rolling, flattening, butt welding, slag planing, rolling, end cutting, rounding, flaring, one-pass rolling, two-pass rolling, three-pass rolling, finishing and air valve hole punching.
