In panel test for spalling resistance, the average face temperature of panel assembly is maintained at ______________ °C for 24 hours?
Correct answer: C. 1600
- A. 700
- B. 1000
- C. 1600
- D. 2000
Explanation
In the panel spalling test, the refractory panel is exposed to a severe high-temperature cycle, with its average face temperature maintained at about 1600°C for 24 hours. The test reveals cracking or disintegration caused by thermal stresses.
