      FRANK EUTECTRON - RANGE OF GAS CARBURISING FLUIDS
      INTRODUCTION
      A non polluting ,thermo chemical process for carburising steels in a pit type furnace.
      PRINCIPLE
      The components to be carburized are charged into furnace fitted with a retort wherein       the  given carburizing fluid is fed under a controlled flow and cracked within the retort       to provide a uniform gaseous atmosphere rich in carbon.    
 
      PROCESS

      1. Remove all contaminants like oil , grease etc. from the components and fixtures           prior to loading.
      2. Raise retort temp. to around 850 deg. ,load the components and ensure leak proof           sealing of the furnace.
      3. Slowly start drip feeding of the carburising fluid and control using the flow meter.
      4. Set fire to the waste gas and adjust temperature and feed as desired.
 
      PRODUCTS
      FRANK EUTECTRON gas carburizing fluids are available in four different variants       with  varying carbon potential for obtaining a range of case depths .
