The UNISEAL® booster for silicon steel are perfect for achieving the highest heating rate under the most challenging working conditions within any silicon steel cold rolling mills. Heating with up to 100 % hydrogen content can be attained.

To resist such difficult working conditions, Inductotherm has developed the most advanced sealing system. This patented system ensures the longevity of the inductor with accurate and safe control of the gas tightness.

This design combines the best refractory material and one or two flexible gas tight sleeves. The inductor is placed on the top of those layers, protected from high temperature without any sealing issues. It allows:

  • to obtain very high heating rates
  • to withstand to very high ambient temperature (annealing furnace ambient temperature) up to 900…1000°C
  • to heat under hydrogen atmosphere and to control continuously the tightness of the inductor.
