The Introduction of the LF Refining Function and Process

Abstract:

The process of LF Refining is introduced in this paper.The LF method is a ladle without vacuum equipment can arc refining method.Because the LF ladle furnace has the advantages of simple equipment, low investment cost, flexible operation and excellent refined effect, are widely used and developed in many countries.The argon is blown from the bottom of the ladle, and molten steel is heated by the graphite electrode, so the purpose of refiningis achieved. The argon stirring can accelerate the chemical reaction between slag and steel.LF refining function includes reductive atmosphere, submerged arc heating, argon stirring and white slag refining.
