As LFS is composed by 50% of CaO approximately, one of the applications is exactly in ladle furnace, in substitution of the quicklime additive [7, 8,9]. However, the entire ladle furnace process Applications - ScienceDirectJan 01, 2014 · After the BOF process, liquid steel containing C < 0.05 wt% is tapped in a ladle. Since liquid steel after the BOF still contains a high amount of oxygen (> 0.05 wt%) and other impurities such as C, S, P, and H, a secondary steelmaking process (also called ladle refining process) is necessary to produce clean steels. Calorised & Ceramic Coated Oxygen Lance Shinto lance OD1''When using Calorised Ceramic Coated Lance, the consumption rate will improve 6-7 times.
