ladle furnace(LF)

Ladle furnace is used to redining of molten steel from primary furnace such as EAF, converter.

usage :

Ladle furnace is used to redining of molten steel from primary furnace such as EAF, converter. It has furctions like normal voltage heating, bottom argon blowing stirring, desulfurization, white slag forming, alloy composition trimming. It is an important equipment of the trinity short process of primary smelting,refining,CCM.

equipment characteristics :

LF ladle redining furnace in the form of the structure is divided into a heating tray,fourth column, arm rotation and revolving table, for users to choose.
