Roller Hearth Kiln (RHK) is a continuous firing furnace which transports products using ceramic rollers.
RHK provides outstanding temperature uniformity, cleanliness and heat efficiency.

  • Uniform Temperature Distribution: RHK’s roller transportation method makes radiant heating from all direction possible and narrows temperature distribution to ±2°C.
  • High Speed Firing: NORITAKE adopts Spring Drive method for the roller transportation drive. This allows for high speed transfer without meandering.
  • Clean Atmosphere: RHK materials are composed of ceramics which helps maintain a clean atmosphere.
  • Energy Saving and Space Saving: The combination of uniform heating and high speed firing realize high efficient production energy saving and space saving.
