What is Fused Cast Mullite brick?

Fused cast mullite brick, or fusion-cast mullite brick, is a type of refractory brick made from mullite clinker. The average alumina content is between 65% and 75%. It is manufactured in an arc melting furnace to completely melt the mullite clinker. The molten material is then poured into a mold to make the refractory brick.

Application of fused cast mullite brick

The fused cast mullite series is mainly used in fields where refractory products with high temperature resistance and excellent wear resistance are needed.

Advantages of AGRM fused cast mullite refractory

The refractoriness can reach 1790 °C. It has high-temperature resistance, wear resistance, and strong corrosion resistance. The thermal expansion coefficient is small. The thermal conductivity is also high, so the thermal shock resistance is better than that of other fused-cast bricks.
