Corundum-mullite castable is a high-quality, high-performance refractory material. Corundum has high thermal conductivity, insulation, good chemical stability and the ability to resist the action of reducing agents.
As the main aggregate, it can make the aluminum content of the castable reach a higher level, significantly improving the hardness and strength of the castable.
Adding mullite to the castable, combined with corundum, can optimize the performance of the castable, making it more outstanding in terms of stability at high temperatures, thermal shock resistance, etc.
(1) Good high temperature strength
(2) Good thermal shock resistance
(3) Wear resistance and erosion resistance
(4) Strong chemical stability
(5) Good volume stability
(6) High load softening temperature
(7) Low high temperature creep rate
