Ladle Secondary Refining Furnace
LF-100t ladle refining furnace has the outstanding design features: operation with submerged “long arc” under synthetic slag at normal pressure, bottom stirring with blowing argon, temperature measuring, sampling, microalloying, deoxidizing, desulphating, purificating, etc. It assures quality and/or productivity improvements in steelmaking. It has exact temperature adjustment for continuous casting and steel composition(metallurgical fine-tuning). It has also the buffer function between melting and casting.

Application:
Ladle refining furnace belongs to the secondary refining equipment, which typically to be used follows the primary melting furnace. Its main function is remove sulfur, impurity from molten steel and adjust chemical components, thereby, improve quality of molten steel. LF is mainly used in high-quality carbon steel, stainless steel, manganese steel and other metal smelting.
Features:
1. LF is not available for smelting, which is just used to provide good reduction reaction environment for molten steel.
2. LF refining furnace is ladle as smelting vessel, with blowing argon stirring, can achieve a better affect of removing sulfur, impurities, as well as adjusting the composition of the alloy.
3. If the primary smelting equipment is induction furnace, the follows LF, which can improve the quality of molten steel, completely finish adjusting the alloy composition.(such as carbon steel can be adjusted as stainless steel or other types of steel in LF)
4. If the primary smelting equipment is EAF, then follows LF, which can replace the arc furnace to finish the refining process of molten steel, at the same time, arc furnace only as a melting furnace. This method can significantly improve the smelting efficiency.
