Seamless Ring Rolling Forging Process

The production of seamless forged rings is often performed by a process called ring rolling on rolling mills. These mills vary in size to produce forged rings with outside diameters of just a few inches to over 300 inches and in weights from a single pound up to over 300,000 pounds. YouTube.

The Process of Galvanizing Steel

opposed to electro-galvanizing, which is a plating process comparable to chroming. After the steel has been thoroughly cleaned, annealed, and cooled to a temperature that roughly matches that of the molten zinc bath, the strip enters the zinc pot and travels around a 'pot roll' which redirects it up through an 'air knife' system.

The Benefits of Roll Forming

Aug 06, 2012· Aug 6, 2012. Roll forming is a flexible and cost-effective process for shaping metal into custom cross-section profiles. Often called "cold roll forming," because the metal is shaped in its hardened state, roll forming is used across a wide range of industries to produce parts and components for everything from metal forming in automobiles to appliances to airplanes and houses.

Modern mills have as many as four sets of rollers, one above the other, and steel is rolled in a continuous process through one set, into another, and then back again, until the desired shape is achieved. Semifinishing mills roll the steel into rectangular shapes to be further refined; finishing mills produce steel ready for use in manufacturing.
