Allegheny Ludlum has awarded LOI Inc., Canonsburg, Pa., a contract to remove and replace the existing 90-line, annealing furnace. The new strip catenary annealing furnace, to be located at Allegheny Ludlum's plant in Vandergrift, Pa., will incorporate latest technology in high velocity, low NOx burners, lightweight fiber insulation and design modifications to provide for additional line speed. Scheduled for installation this month, LOI is having the furnace shop assembled to keep field time to a minimum.
