Abstract
The invention provides a colloidal refractory system for an electric arc furnace or another pyrometallurgical converter having a hearth, a shell, and a roof. The colloidal silica refractory includes alumina having a range of about 55 percent through about 90 percent by weight, silicon carbide having a range of about 2.5 percent through about 30 percent by weight, silica having a range of about 2 percent through about 20 percent by weight, and carbon having a range of about 0.1 percent through about 4 percent by weight. An aqueous colloidal silica binder provides the silica. The colloidal refractory system has high-temperature strength and resists the attack from slag and off-gases.
