Lindberg/MPH, Riverside, Mich., has shipped a gas-fired aluminum stack melting furnace to a leading supplier 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.
“At Lindberg/MPH we work with our customers to provide the most efficient solutions to their production needs,” said Lindberg’s Andrew Paul.” For this customer, hooking into their existing equipment was the most effective solution to increase their melting capacity. This furnace provided the flexibility to increase their melting capacity by adding to their existing equipment instead of installing an entirely new furnace.”
