JXGQ-80
By adding heat-resistant stainless-steel fibres, the high-temperature toughness of the castable and its resistance to mechanical vibration and impact are further increased while its original high-temperature properties are retained, extending service life. Suitable for the kiln outlet, burner pipe, kiln hood and similar areas of cement kilns.
