PCE value (Segar cone) of Superduty refractories is more than 33, which is equivalent to a temperature of ____________ °C?
Correct answer: D. 1730
- A. 1520
- B. 1630
- C. 1670
- D. 1730
Explanation
A Seger cone above cone 33 corresponds approximately to 1730°C. PCE is a heat-resistance measurement based on the softening and bending of the refractory cone under standard conditions.
