Sulfur Control in Ultra-Low Sulfur Steel Refined by Ladle

2014-3-4  Ultra-low sulfur steel is produced by the basic oxygen furnace-ladle furnace (LF)- Ruhrstahl-Heraeus-Ca-treatment-continuous casting method. The effect of (FeO+MnO) content in the LF slag, the kinetic conditions for LF refining and vacuum degassing (VD) with late calcium treatment on desulfurization were studied.

Ladle refining [SubsTech]

Molten steel in a ladle may be treated (refined) in a device called Ladle Furnace (LF). The ladle is transported to the Ladle Furnace stand where it is placed under a cover equipped with three graphite electrodes connected to a three-phase arc transformer. The ladle bottom has a porous refractory plug, which is connected to the argon supply pipe at the Ladle Furnace stand.
