Usually, metal sheets are made of different layers of metals. In four high rolling mills, there are four rollers rolls in the opposite direction. The ring rolling process starts with a circular preform of metal that has been previously upset and pierced (using the open die forging process) to form a hollow “doughnut.” This doughnut is heated above the recrystallization temperature and placed over the idler or mandrel roll. The metal sheet is passed through rotating rollers which put pressure on the sheet.

Over the last decade, the industry is moving away from the traditional manufacturing process like casting, forging, etc, and adopting sheet metal. Static forecasts use a count-down process. The process and equipment are similar in principle to rolling mills used for plate. The spray-up application of gel coats is especially problematic and it produces high styrene emission rates. Ring rolling is a hot forming process that produces seamless rings varying in size from a few inches in diameter, and weighing less than one pound, to over 25 feet in diameter and face heights approaching 10 feet.
