Characterization of Ladle Furnace Slag from Carbon Steel ...

A promising type of steel slag for applications is the ladle furnace (LF) slag, which is also known as the basic slag, the reducing slag, the white slag, and the secondary refining slag. The LF slag is a byproduct from further refining molten steel after coming out of a basic oxygen furnace (BOF) or an electric arc furnace (EAF).Slag Formation Œ Thermodynamic and Kinetic Aspects …2018-9-8 · Figure 1. Typical slag paths during BOF blow presented in ternary diagram of main slag constituents. During the oxygen blow the slag temperature rises from 1300 ⁰C to 1700 ⁰C [9]. Principally, another way to promote slag formation is to add compounds, which "flux" the silicate nose by shifting the Ca. 2. SiO. 4
