Ambient weathering of steelmaking ladle slags

 · The steelmaking slag formed in the ladle, where the secondary metallurgy occurs (and the final steel chemical composition is adjusted), is known as white slag or LFS (Ladle Furnace Slag). At operating temperature (1600–1700 °C), this slag floats over the liquid metal, and continuous stirring by argon gas blowing helps displacing the impurities from the metal to the molten slag.

Alkali Activation of Ladle Slag from Steel-Making Process
