High Aluminum Series Refractory Castable
【Performance Characteristics】
The integrity would be higher when refractory steel fiber is added in accordance with application requirement.
【Using Position】
LM-L55/ LM-L60:Rear of cement kiln cooler and other industrial furnace liner
LM-L65/ LM-L70:High temperature resistance positions such as cement kiln entrance cover and front-end of cooler, and other industrial furnace liner
LM-L75:High temperature resistance positions such as the front and the back hoods and kiln entrance cover of cement kiln and the front-end of cooler.
