Thermal shock resistant Mullite refractory brick Low creep kiln refractory material
for Steel Industry
Mullite Refractory Brick uses high-quality mullite as aggregate, matrix fused white corundum powder, mullite powder, clay, and mixed powder prepared in advance, added in right amount "three stone": kyanite, andalusite, sillimanite, through reasonable grading, molding by high pressure, and firing by high temperature.
Mullite Refractory Brick provided by us with features of low creep, good resistance to thermal shock, high temperature volume stability, high temperature bending strengthetc. The bricks are widely used in steel and many other special parts of the industry.
