Lindberg/MPH announced the shipment of a gas-fired aluminum stack melting furnace for a leader in the marine industry. The industrial furnace was modified to hook directly to the customer’s existing melting furnace to provide additional melting capacity and efficiency.

The customer requested a system that would increase melt rate, enhance safety, and improve efficiency with state of the art process control. Lindberg/MPH took the customer’s request and designed a stack melting system to attach to the customer’s existing melting furnace via a short and enclosed launder connection trough. The two manually operated doors on adjacent sides allow for easy access to the melting chamber for cleaning. The laser charge stack level control monitors material level in the stack for maximum efficiency. A service technician provided by Lindberg/MPH will perform supervision during the installation period and perform onsite start-up and training.

The stack melt zone of the industrial furnace consists of a sloped charging stack that helps to minimize impact damage from ingot or large heavy scrap. Instead of falling directly onto the impact zone it slides and tumbles to the bottom of the charging stack. At the intersection of the stack and hearth the metal begins to melt. Additional material that is charged in the stack is preheated until the metal below it becomes molten and runs off the hearth through the flanged connector into the separate customer supplied melting and holding furnace.

Unique features of this aluminum melting furnace include:

• Rugged steel construction
• Impact resistant castable lining
• Two side access cleaning doors
• Installation supervision and start-up
• Integrated programmable logic process controller
• Laser charge stack level control
