What is fused cast refractories

Fused cast refractories are manufactured by melting mixtures of raw material of the desired composition in an electric furnace at a temperature exceeding 2000°C, casting the melt into moulds where it solidifies and cooling the molten refractory material to form a solidified refractory. High density, small or large shapes are obtained. When appropriate, a finish is made by grinding with diamond tools to a very tight dimensional control and superior surface quality.

Such refractories have presented many advantages in certain uses over the older type of refractory products. They are denser & more corrosion-resistant than fired & unfired bonded refractories and is available in many shapes & sized, and is produced with and without casting voids.


Besides glass industry, Fused cast refractory materials are also used in many other industries such as iron & steel, aluminum, petrochemical  or wear resistant applications.

So far many different compositions for fused cast refractories have been developed, such as Fused cast AZS block, Fused cast Alpha-Beta alumina,Fused cast Alpha alumina,Fused cast Beta alumina,fused cast mullite and Fused cast high zirconia block.
