Inclusion steel wettability
WebSep 15, 2024 · When two solid inclusions approach each other in the molten steel with a narrow space, a gas cavity is formed between inclusions due to the poor wettability, as shown in Figure 2. The profile of the meniscus (gas–liquid interface) can be approximated by a circular arc. The curvature radius of the meniscus and the radius of the WebThe inclusion particles that reach an equilibrium state at the steel-slag interface are subject to re-entrainment back into the steel, due to lift forces applied to them by the turbulent …
