It is made by adding inconsistent material with high alumina bauxite in high alumina brick, to produce micro cracks in product structure by using the principle of complex phase toughening, which relieves or cuts off the damage caused by the thermal stress and strengthens the corrosion performances of high temperature and chemicals at the same time to realize more than three times longer life than that of traditional high alumina brick.
1. Spalling resistance.
2. High refractoriness under load.
Belt of transition, wicket cover, decomposition furnace and other parts of cement rotary kiln.
