Refractoriness of a typical silica brick corresponds to Segar cone number, '32', which is equivalent to a temperature of _____________ °C?
Correct answer: C. 1710
- A. 1380
- B. 1520
- C. 1710
- D. 1915
Explanation
Seger cone 32 corresponds approximately to 1710°C, placing it among the high-temperature silica-brick refractoriness grades.
