Stabilization of Refining Slag by Adjusting Its Phase Composition and Giving It the Properties of Mineral Binders

详细

Refining slag used in out-of-furnace metal processing units, due to significant content in it of the unstable phase—dicalcium silicate, is prone to decay due to its polymorphous transformations, accompanied by an increase in the volume of the crystal lattice. Getting into cracks of the furnace lining, the slag can cause its destruction. The results of investigating the mechanism of stabilizing the refining slag by introducing alumina flux to it, while giving it the properties of mineral binders, are presented here.
