Mullite castable series material

High strength in high temperature: the high-performance mullite castable takes the high-purity excellent mullite as raw material, control the basic ingredient strictly, so that form the mullite bone structure, improve the strength of the castable, strengthen the anti-corrosion of the castable and prolong the operation life. Good thermal shock resistance: since the thermal expansion coefficient of the mullite for 5.7x10-6/, good stability in volume, meanwhile the mullite is the rod-shape crystal, and its thermal expansion is aeolotropy, so the internal of the pouring material can form a lot of minor crackles during firing which will improve the tenacity of the castable, buffer the thermal stress and stop the crack extending. The high-performance mullite castable has the advantages of high performance in Good thermal shock resistance, anti-peeling, good stability in hot vibration, high soften point with load, small creeping strength value at high temperature, high hardness and excellent in anti-corrosion etc.
