a lot of effort for a device with a very specialized heating potential
basically X length of some given cross section, reheating odd shapes becomes problematic
dimension flexibility isnt very cost effective
environmental controls could be whatever you want with an additional step in complexity, natively the rapid heating means less oxygen exposure
if your working a specific dimension again and again it might make sense
Induction heating Induction furnace High Frequency Induction Heating Induction Heating - Amps, Volts, and Watts Crucibles for Induction Melting
note magnetic fields obey the
inverse square law the larger the area you have to heat (flexible space) the stronger the field strength and higher the energy cost will be, in addition exposure to heightened
electromagnetic radiation at those frequencies is
arguably hazardous while
shielding is relatively easy its yet another level of complexity. Electromagnetic interference might be an issue with susceptible devices depending on how close they are.
