Tenova Core, in conjunction with Tenova Pyromet, has been contracted to design and supply a 12.5-MVA submerged arc furnace (SAF) for Armstrong World Industries’ new 30,000-square-foot manufacturing plant in Millwood, W.V. 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. The SAF installation is expected to be completed in 2011, and the plant will be in full production in 2012.
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. Some product will also go through Fibrox Inc. to a variety of commercial and industrial applications, including building products, fire protection, insulation and friction materials.
