| 摘要 |
The invention relates to a refractory material for cement industry kilns and the use thereof. The inventive material can be used inside cement industry kilns in order to counteract the thermal and physico-chemical deformation that occur inside the kilns. The inventive composition is based on a combination comprising at least 10% by weight of andalusite (Al2SiO5), at least 10% by weight of silicon carbide (SiC) and at least 5% by weight of clay. Moreover, kaolinite (Al2Si2O5(OH)4) can be used instead of andalusite in equal proportions. The refractory material can be used to line the inside of the cement kilns in the calcination areas (2), in the kiln outlet (6) and in the coolers (7).
