Powder firing furnace

Features

  • Various atmosphere gas
    operation based on vacuum
    replacement

  • Specialized in high
    temperature firing of 1500 ~
    2500℃ for powders such as
    ceramics or carbon

  • Considerations for uniform
    contact between process
    gas and powder

  • Batch type of single rotary
    retort or pulse type of
    continuous multi-chambers

  • Utmost productivity and
    economy without using
    crucible
