LF Ladle Refining Furnace Introduce

Ladle arc furnaceApplication


LF-typed ladle refining furnace is used for refining molten steel from primary melting furnace (EAF or Convertor), can create a slightly positive pressure reducing atmosphere, apply such means as submerged arc heating, argon stirring, white slag refining, alloy composition trimming, wire feeding under the atmosphere to conduct degassing, desulfuration, decontamination for hot metal, and accurately control the ingredients and temperature of molten steel. The equipment also has an effect of buffering and adjusting continuous casting links.
 
It consists of:


Transformer for electric furnace, Network, Electrode lifting and lowering device, Ladle lid and ladle lid lifting and lowering device, Heating bridge frame, Steel ladle, Ladle carrier, Wire feeder, Argon regulating system, Water cooling system, Compressed air system, Hydraulic system, Temperature measurement and sampling system, Automatic charging system, High-voltage power supply system, Low-voltage electrical control system and automation system, etc.
 
Type of LF Furnace :


Bridge type or the type with independent rack mount and furnace cover; single arm or three-arm; ladle revolving platform or furnace lid rotary type, etc.
