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:
uEven the molten steel composition and temperature
uDesulfidation, Degassing, deoxidation and remove non-metallic impurities.
uIncrease production capacity.
Adoption of new technology:
uElectrode lifting mechanism ( single phase, three phase)
uOptimize large current system structure (energy-saving type)
uPLC controller of electrode automatic lifting regulator
uAutomatic control argon blowing system
uFrequency control ladle car
uIndustrial automatic control
uNetwork technique
