Apr 04, 2012 D. Sichen, in Fundamentals of Metallurgy, 2005 9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag–metal reactions.

Stabilization of Stainless Steel Slag via Air Granulation

Feb 08, 2019 In stainless steel production, slag from argon oxygen decarburization (AOD) converters is dumped on to the ground and then slowly cooled. The slag undergoes phase transformation from β-dicalcium silicate (β-C2S) to γ-dicalcium silicate (γ-C2S) at approximately 500 °C to 450 °C, resulting in slag volume expansion, disintegration, and dust generation.

Slag Wikipedia

Ferrous and non-ferrous smelting processes produce different slags. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags.. Steel. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly
