Corundum mullite brick is made of high-purity fused aggregate, ultrafine powder and composite admixture through high pressure forming and high temperature sintering. It has excellent characteristics such as high temperature resistance, erosion resistance, corrosion resistance and thermal shock stability.
Corundum Mullite Bricks Features:
1.Uniform expansion.
2.High load softening point.
3.Low temperature creep value.
4.Excellent thermal shock stability.
5.High load softening temperature.
6.High hardness, good chemical resistance.
7. Low creep rate, good thermal shock resistance
Corundum Mullite Bricks Application:
1.Corundum mullite bricks suitable for large and medium sized blast furnace bottom.
2.Corundum mullite refractory bricks suitable for hearth ceramic masonry and wind, iron, slag joint masonry.
3.Corundum mullite fire bricks suitable for glass furnace superstructure brick, material brick, cover plate, molded parts.
4.Corundum mullite fire bricks suitable for medium temperature carbon black reactor lining and other Thermal equipment lining.
