A new heat-treating line, claimed to be one of the most advanced turnkey heat-treating lines in the world, helped improve production and quality of parts weighing up to 15 metric tons.
FRISA Forjados S.A. de C.V. has been producing seamless rolled carbon steel, alloy, and stainless steel rings for more than 30 years. Founded in 1971 as a small forge shop, FRISA has grown into one of the world's leading manufacturers of these components. The rings, with up 20 ft (6 m) diameter and weighing up to 15 metric tons, are used as bearings, valve pieces, gears, flanges, fittings and valves in oil rigs, cement processing plants, mining, energy production, construction and transportation equipment. For example, 5-ft (1.5 m) diameter rings might be used as wheel rims in mining trucks, while 12-ft (3.6 m) diameter rings might be used in steam turbines in power generation. They are also used in deep-water equipment such as connectors, blowout preventers, buckle arrestors, and risers, as well as in steam and gas turbines, eolic generators, flanges for eolic towers, pelletizers and locomotive parts (Fig. 1).
