MPEI scientists have created a new setup to heat spinning disks and parts using permanent magnets. This heating method increases efficiency by up to 90% and significantly increases the heating efficiency of rotating parts.
Using the ANSYS software package and 3D modeling, the researchers demonstrated that an electromagnetic field created by permanent magnets and with a residual induction of 1 Tesla effectively heats metal spinning disks. Permanent magnets are made of a special alloy.
NRU MPEI Rector Nikolai Rogalev noted that in the context of import substitution, it is very important to develop energy-efficient heating methods that do not require additional power supply and cooling systems. Such installations can reduce material and energy costs.
The experiment showed that the discs reached a temperature of 200-250 °C in 40 seconds. Permanent magnets have a braking effect on the rotation of the disc by interacting with eddy currents in the material of the disc. The developed heating method can be applied to small-sized rotating discs and parts in various industries such as aerospace, mechanical engineering and metallurgy.
