Effect of Viscosity and Interfacial Tension on Metal Content in Slags,
Abstract
The problem of separating metal from slag is of enormous significance for the economics of steel production. One of the main indexes for steel quality is the degree of its purification from nonmetallic inclusions. With a reduction in the content of metal globules in the slag, the losses of the metal carried away in the slag are reduced. In this regard, a substantial role is played by the ratio between the force of interaction of the ions in the heat, and the bonding between the surface layers of the slag and the metal. When the interion interaction in the molten slag is weaker, its surface layer adheres more strongly to the metal, and it is very difficult to separate the slag from the iron in pouring it from the metallurgical unit.
