"MAGHEAT" Usage Example: Preheating in the warm spinning process.

"MAGHEAT" allows for localized heating, so by selectively heating the spinning processing areas of near-net shape, processes such as submerged cooling are unnecessary!

Our "MAGHEAT" is a magnetic induction heating device that generates induced currents by moving magnets, allowing non-ferrous metals to be heated using the resulting Joule heat. It employs a motor as its power source, making it possible to reduce power consumption. 【Example Application: Preheating in the Warm Spinning Process of Aluminum Wheels】 In the process of finishing the rim shape of near-net-shape wheel castings through warm spinning processing, the wheels are heated to 350°C to 400°C using a gas furnace, then the front design surface is submerged and cooled to 150°C before the spinning process. However, "MAGHEAT" allows for localized heating, enabling selective heating of the spinning processing areas of near-net-shape parts, thus eliminating the need for processes like submerged cooling. Currently, heating with a gas furnace requires about one hour of heating in the furnace to evenly heat the wheels to 350°C to 400°C, but "MAGHEAT" can achieve uniform heating in about 5 minutes, eliminating the need for water cooling processes. ★ Gas cost with gas furnace = 76.39 yen per unit ★ Electricity cost with MAGHEAT = 3.84 yen per unit *For more details on significant reductions in heating costs, please refer to the materials available for download below "PDF Download."
