Cogemikanit is a trade name for a plate coating material, which is used in induction furnace construction as an electrical insulation and separating agent on the crucible between the wear crucible and the coil plastering.
Plate thicknesses of 0.5 to 2.5 mm can be treated. Above 2.5 mm, the plates are no longer mobile enough, and their application possibilities are therefore limited. There are thicknesses of 0.4; 0.5; 0.6; 0.8; and 1.0 mm on rolls with a width of 1,000 mm and lengths of 10 to 25 m, depending on the thickness.
A special version is Cogemikanit with internal “fly screening” and an outer layer of 0.5 mm micanite for the connection of monitoring systems in crucible furnaces. Iron piles are insulated against the coil outer jacket with 2 mm of Isoplan and depending on the operating voltage, with 2x 0.5 to 6x 0.5 mm of Cogemikanit at 3,000 volts.
