Refractory Castables

Refractory Castable lining in the discharge zone of the rotary kiln is always considered as critical by kiln operators, designers and refractory suppliers. The necessity to run the rotary kiln without frequent stoppages has forced the kiln users to look for continuous improvement in castable usage practice. The discharge zone consists of Tip Casting, Burner Pipe, and Bull Nose areas where the castables are predominantly used apart from cyclone and cooler areas.

The kiln users look forward to an optimal life, which should normally synchronize with kiln shutdown schedules/multiples thereof and the industry do not want any stoppage on account of refractory castable repair in between shutdowns. The frequent forced stoppages due to market conditions should also not affect the castable due to thermal shocks and the user expects lining to be stable and withstand the forced stoppages. Appearance of hotspot in the discharge end also results in forced stoppage to carry-out repairs.

Therefore the castable lining should not have a catastrophic failure and all these above conditions have lead to fine-tuning of the proven Low Cement Castable Technology to specific needs of the cement industry. Low cement castables with high abrasion/alkali resistance aggregates and high performance bond are being practiced in various kiln's Tip casting/Burner Pipe/Bull nose areas and products installed are performing well with respect to above conditions. Usage of low cement Castables improves discipline amongst operating personnel during application resulting in better performance.

It has been reported that kiln users are able to plan their schedules without worrying on castable performance. Our service engineers do have a database on each kiln serviced by them to continuously improve the performance. Our database shows that castable lining offer opportunity to reduce cost/MT of clinker produced and we have been able to work towards these objectives. For less than 1 MTPA capacity kilns, the user friendly cablecast Thermo Patch, have been standardized in various plants to derive reliability of the lining and for bigger plants, Low Cement Castables are recommended.
