Integrated refractory packages for rotary kilns, preheaters, precalciners and grate coolers.
Cement kilns run above 1450℃ with clinker coating, alkali-vapor attack and abrasion. The company supplies high-alumina and spalling-resistant bricks, SiC castables and precast blocks for transition and burning zones, preheater stages, precalciners and grate coolers — extending lining life and shortening overhaul time.
Typical kilns in this industry — click each to see its specific problems and solutions
The rotary kiln burning zone exceeds 1400°C; coating stability determines magnesia brick life, while the transition zone faces thermal shock and mechanical stress.
View Problems & Solutions →Preheater cyclones and the precalciner suffer build-up from alkali/chlorine/sulfur cycles; anti-build-up and wear-resistant linings are key.
View Problems & Solutions →The grate cooler hot end absorbs clinker drop impact and secondary-air abrasion; heavy-duty steel-fiber wear-resistant castables are widely used.
View Problems & Solutions →The kiln hood connects the rotary kiln and grate cooler; suspended roof structure and side-wall thermal shock resistance drive maintenance.

Frequent thermal shocks caused nose castable spalling. High-alumina/corundum precast blocks replaced cast-in-place lining, lifting life by about 40% and extending the maintenance cycle from 6 to 9 months.
