『MAGHEAT』 Application Example: Preheating of Aluminum Ingots at the Melting Plant
By preheating the aluminum ingots to 450℃ to 500℃ and then charging them into the melting furnace, it is possible to achieve complete melting in the furnace in about 10 minutes!
Our "MAGHEAT" is a magnetic induction heating device that generates induced currents in non-ferrous metals by moving magnets, utilizing the resulting Joule heat for heating. It employs a motor as a power source, allowing for reduced power consumption. [Application Example: Preheating Aluminum Ingots in Aluminum Melting Plants] Recently, attention has been drawn to preheating ingots to approximately 450°C to 500°C with "MAGHEAT" before introducing them into the molten bath. Currently, ingots at room temperature are being introduced into tower-type melting furnaces, causing them to drop to the bottom of the molten bath upon entry, damaging the furnace floor and generating a large amount of oxides. For a 10 kg ingot, it is said to take about one hour to dissolve in the molten bath. By introducing preheated ingots at 450°C to 500°C, it is possible to achieve complete melting of the entire bath within 5 to 10 minutes. In gas furnaces, the preheating temperature is "MAX 250°C," whereas with MAGHEAT, a preheating temperature of around "500°C" is achievable. *For more details on this application example, please refer to the materials available for download below "PDF Download."
