A multinational aluminum producer ordered a new 100,000 lb. capacity tilt melting aluminum furnace for one of their regional aluminum extrusion plants. Fabricated in PA, the furnace will incorporate several features to meet the manufacturer’s efficiency, production, and capacity requirements, as well as options to accelerate melting and transfer flow.
SECO/WARWICK USA will fabricate this aluminum reverb furnace. “Most of the damage to a furnace like this is from loading it with a forklift,” comments Marcus Lord, managing director at SECO/WARWICK USA. “Either bumping into the refractory around the door or being a bit clumsy with large awkward chunks of aluminum. It means the door is open a lot, and when it is closed, it might not have the best seal because the sills, jams and lentils are all beaten up. This furnace has a separate loading mechanism, so the door doesn’t need to open nearly as often. It really extends the life of the refractory, but it’s a huge efficiency boost too.”
This furnace will be fabricated with additional features, including capabilities to allow for a magnetic stirrer (supplied by the client) to be mounted under the furnace, saving more energy by increasing the melt rate by up to 10%. It will be capable of completely one full batch cycle in under 6 hours, for four batches a day, yielding a total of 340,000 to 400,000 lbs. per day. These combined factors will result in a fuel economy when the burners are firing in the regenerative mode of less than 1200 BTU per pound during the melt cycle.
