High Strength Alkali-resistant Refractory Castable
High Strength Alkali-resistant Refractory Castable
In the dry process cement preheater, harmful ingredients in raw material, such as alkali, chlorine and sulphur, continuously volatilize and agglomerate, causing strong chemical corrosion and the alkali cracking damage and the alkali cracking daand the alkali cracking dato the refractory inner lining, therefore the refractory at this position requires good alkali resistance behavior. The high strength alkali-resistant pouring materials produced by our company are of good alkali resistance and high strength, gaining affirmation and praise of users in the actual use.
