Chromite-Periclase Refractory Wear in Zinc Production Waelz Kiln Reaction Zone

Abstract

A contemporary procedure is discussed for improving the structure of chromite-periclase refractory based on analyzing corrosive action of a reaction charge fired in aWaelz kiln. It is established that refractory wear during service proceeds by a frontal scheme through a series of successive transformations of the microstructure. On the basis of studying corrosion results for refractory objects of fayalite composition by slag manufacturing technology is developed for chromite-periclase refractories more resistant to Waelz material components.
