Evolution of refractory materials for rotary cement kiln sintering zone

Abstract

Development of refractory materials for the high-temperature zone of the rotary kilns used in the cement industry that is the second-largest user of refractory materials is given in the article. It is shown that the history of refractory materials used in this rotary kiln high-temperature zone commenced with alumina-silicate materials and ended with specially developed periclase-based materials used currently. Advantages and drawbacks of these materials are considered. Basic information is provided about the manufacture of cement for consideration of possible chemical reactions between cement kiln raw material and refractory material components.
