Refractory Lining In Cement Rotary Kiln

2019-9-12  Refractory lining in cement rotary kiln’s heating and cooling system is a key. The kiln-lined alkaline refractory bricks are the most easy to bricks to crack and peel, and their service life is also the shortest because they have the largest thermal expansion coefficient and poor thermal stability, but they are used in the highest temperature zone in kiln.
