Lindberg/MPH, Riverside, Mich., announces the shipment of an aluminum central melting furnace that holds 62,000 pounds of aluminum and has a melt rate of 6000 pounds per hour. The melting furnace is capable of delivering molten aluminum to a transfer ladle through a pneumatic well that has 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 furnace is loaded with aluminum ingot, and sows across a preheat hearth. 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 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 is 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 is a top priority for our customer,” says Andrew Paul, Sales Engineer. “This equipment features options for added safety during the loading and dispensing processes.”
