Lindberg/MPH announced the shipment of an aluminum central melting furnace to the die casting industry. This equipment holds 62,000 lbs. of aluminum and has a melt rate of 6,000 lbs. per hour.

The furnace is loaded with aluminum ingot, and sows across a preheat hearth and returns are fed via conveyor system into an exterior side well that is interconnected to a circulation well equipped with a pump. The aluminum on the hearth receives tremendous preheat before being pushed into the bath which increases efficiency and improves safety.

The melting furnace is capable of delivering molten aluminum to a transfer ladle through the use of a pneumatic well in which there are no moving parts.  Air pressure is applied to the pumper by means of a blower and molten aluminum is forced up a special discharge tube and into a transfer ladle.

The metal temperature is controlled through digital temperature controllers and features automatic preheat and dry out.  The flue gases are controlled with a mechanical flue damper reducing flue losses during low-fire operation.  A three-point laser metal level sensor is provided to notify operators of the current furnace metal level through an attached light tree.  A totalizing gas meter was also included to accurately measure gas usage.  Access grating and ladder are provided for safe access to the roof mounted equipment during maintenance.

“Operator safety was a top priority for our customer. This equipment features options for added safety during the loading and dispensing processes.” Andrew Paul, Sales Engineer
