Coke Calcining | Refractory Products High Heat Application ...

Typical temperatures for a rotary coke calcining kiln are between 2200°F (1200°C) and 2400°F (1315°C). Alumina-silica refractories in the 40% to 70% Al2O3 range are appropriate for these normal operating temperatures. Petroleum coke calcining operators prefer single-layer brick linings using rotary kiln block (RKB''s).
