Lindberg/MPH shipped an 85-foot-long electric resistance-heated aluminum launder system to an aluminum die-casting company. The system will connect the company’s existing gas-fired aluminum melting furnace to three new electric resistance aluminum holding furnaces located at three die-cast machines. Overall, the launder saves energy by eliminating two pours – one from the melting furnace to the transfer ladle and another from the transfer ladle to the holding furnace. It eliminates the oxides and the resulting hard spots that form each time the molten aluminum is disturbed.
The launder also eliminates equipment and manpower costs, as well as the inherent dangers associated with transferring molten aluminum from the melting furnace to the three holding furnaces with forklifts and transfer ladles. It keeps the molten aluminum at a setpoint temperature until it reaches the holding furnaces, which means there is no temperature lost during transfer. The equipment was factory-tested and adjusted prior to shipment to help reduce installation and start-up times.
