WebJun 10, 2024 · ASC refractories have high application temperature as no low melting phase occurs between Al 2 O 3 and C. 2. ASC refractory is a composite of Al 2 O 3 –C with SiC, and it has lower thermal expansion than alumina. 3. Graphite has very high thermal conductivity, which imparts high thermal conductivity in the Al 2 O 3-SiC-C composites. 4. WebThe refractory in a direct-fired rotary kiln is a crucial component, serving to both protect the shell of the drum and combustion chamber from the high interior temperatures, and to minimize heat loss. As a result, protecting refractory is not only critical to promoting optimal efficiency, but also to maintaining and prolonging the life of a ...
