Ladle Refining Furnace Application:
Ladle Refining Furnace is used to refining the molten steel from the 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 the soul of the best production line ( primary melting furnace + LF+ CCM). It is widely used in the refining of kinds of steel grade, such as Ball bearing steel, alloy structural steel, tool steel, spring steel, carbon steel and etc.
Adoption of new technology:
Tubular water cooled furnace lid
Electrode lifting mechanism ( single phase, three phase)
Optimize large current system structure (energy-saving type)
PLC controller of electrode automatic lifting regulator
Automatic control argon blowing system
Frequency control ladle car
Industrial automatic control
Network technique
