Ladle Refining Furnace

 

                                             

 

Ladle Refining Furnace is used to refine the molten steel from primary melting furnace (electric arc furnace, induction furnace, converter and etc.), meanwhile have the function of adjusting molten steel temperature, and be a buffer of the whole process. It is described to be soul of the best production line ( primary melting furnace + LF+ CCM). It is widely used in refining of kinds of steel grade, such as Ball bearing steel, alloy structural steel, tool steel, spring steel, carbon steel and etc. 


Characteristic: 

  1. Even the molten steel composition and temperature
  2. Desulfidation, Degassing, deoxidation and remove non-metallic impurities.
  3. Increase production capacity.

 

Adoption of new technology:

  1. Tubular water cooled furnace lid
  2. Electrode lifting mechanism ( single phase, three phase)
  3. Optimize large current system structure (energy-saving type)
  4. PLC controller of electrode automatic lifting regulator
  5. Automatic control argon blowing system
  6. Frequency control ladle car
  7. Industrial automatic control
  8. Network technique
