Smart refractory solution for stress loaded rotary kilns

Regarding their performance characteristics in cement rotary kilns - particularly under thermomechanical loads - magnesia chromite bricks of the PERILEX (R) 80 type have set new standards. Although this brick grade already features a reduced chrome ore content, the formation of chromates under corresponding conditions cannot be excluded. With PERILEX (R) CF a product is available now, which exhibits the same positive thermomechanical properties as PERILEX (R) 80, but without the use of chrome ore. Further improvements were also achieved by increasing infiltration resistance, coating formation, and even thermoplastic stress relaxation. The concept of the chrome ore free PERILEX (R) has been confirmed in numerous applications, so that a new, innovative and future-proof basic product for the lining of cement rotary kilns is available now.
