Tenova Core to Supply Armstrong World Industries a Submerged Arc Furnace
09/24/2010 - Tenova Core, in conjunction with Tenova Pyromet (South Africa), was contracted recently to design and supply a 12.5-MVA submerged arc furnace for Armstrong World Industries’ new 30,000-square-foot manufacturing plant, located in Millwood, West Virginia.
Tenova Core, in conjunction with Tenova Pyromet (South Africa), has been contracted recently to design and supply a 12.5-MVA submerged arc furnace (SAF) for Armstrong World Industries’ new 30,000-square-foot manufacturing plant, located in Millwood, West Virginia.
The SAF will feature advanced electrode clamping technology and a single-phase transformer with three independent on-load tap changes as well as state-of-the-art process control systems.
The Armstrong plant will manufacture mineral fiber, an inorganic, vitreous material made from blast furnace slag, ferroalloys smelter slag and other molten minerals and then spun at high temperatures. The final product is primarily a feed material for Armstrong’s ceiling plants.
Some product will go through Fibrox Inc. to a variety of commercial and industrial applications, including building products, fire protection, insulation, and friction materials. Armstrong is said to have selected the Millwood site because of a competitive electricity market, proximity to raw material suppliers, as well as a central location in relation to other Armstrong manufacturing facilities.
The SAF installation is expected to be completed in 2011, and the plant is scheduled to be in full production in 2012.
Tenova Core is a leader for the design and supply of reheating, heat treating, specialty and carbon processing furnaces as well as melt shop equipment, technical services, and automation systems.
Tenova Pyromet has experience in the design and construction of smelting plants and furnaces, both in South Africa and internationally.
Tenova designs and supplies advanced technologies, products, and services for the metals and mining industries. The company operates close to its customers through a network of 33 companies based on five continents.
