Whenever gas passes through a liquid, the liquid expands due to the presence of the gas. During steel-making, oxygen lancing causes formation of stable slag foam bubbles on top of the molten hot metal. While some foam is desirable to help capture the energy from post combustion, excessive foaming can lead to slopping in oxygen steel-making.
