Roller kilns fire fast, stressing walls with frequent thermal shock; spall-resistant bricks and suspended roof slabs are preferred.
Problem-by-problem analysis with solutions and recommended refractories
Castable precast blocks are factory-cast, cured and fired to drawings with ±2mm dimensional accuracy, 1700℃ max service. Uniform quality with crane-installed placement that eliminates formwork, casting and curing—dramatically shortening outage time.

Mullite castable with mullite clinker or synthetic aggregate, Al₂O₃≥75%, 1650℃ max service. High refractoriness-under-load with excellent creep and thermal-shock resistance for long-term load-bearing at temperature.
Learn More →Intermittent kiln for ceramics firing, frequent heating/cooling cycles; thermal shock and deformation of wall/roof refractories are prominent
View Problems & Solutions →Tunnel kiln car linings face repeated heating and load abrasion; burning-zone brickwork and car tops are the critical zones.
