Application
Ladle refining furnace belongs to the secondary refining equipment, which typically to be used
follows the primary melting furnace. Its main function is to 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, manganess steel and other metal smelting.
