alkali resistant refractory castable for lining of cement kiln preheater with good wear-resistance performance
Alkali resistant refractory castable is made of high-silica and Alkali-resistant ceramic particles.In use, when the alkali gas is eroded, the high-silicon low-aluminum component reacts with the alkali gas to form a high viscosity liquid Phase, attached to the surface of the castable, and the use of modern ultrafine powder technology, significantly improved its strength.
Properties of Alkali resistant refractory castable:
1.the good construction mobility,
2.construction is simple,
3.simple maintenance and other fine features.
