Fireclay Brick — Refractoriness Under Load (RUL)

The graph shows the result of an RUL test on a test piece taken from a fireclay brick (approx. 35% Al₂O₃);Test conditions: 0.2 N/mm²; 5 K/min; static air.At 960°C the test piece reaches its maximum expansion. Deformations of 0.5%, 1.0% and 2.0% have been achieved at 1210°C (T05), 1240°C (T1), and 1270°C (T2) respectively.
