The authors assess the performance of a mullite-corundum refractory in the roof of an arc furnace on the basis of its pore structure, temperature resistance, scaling, thermal conductivity, compression strength, deformability, and its contribution to the overall thermal efficiency and reduced electrical power consumption of the furnace. Comparative tests are run against periclase-chromite refractories. The mullite-corundum versions are found to possess superior thermal resistance and service life.
