Aluminum-silica series refractory bricks mainly include alkali-resistant series bricks, high-alumina (anti-stripping) series bricks, silicon-mo series bricks and so on.. The upper transition zone of the rotary kiln is close to the firing zone and the firing zone. The flame temperature of the lining can reach up to 2000℃, and the temperature of the material can reach 1350~1400℃.

Castable refractory is being poured into the door of a rotary kiln. Y anchors can be seen. Castable refractory has a similar material cost to brick. However, brick installation is much more labor intensive, as each brick is individually installed. This makes the overall cost of a brick lining more expensive than a castable one.
