Pyrometric cone equivalent (PCE) value (Segar cone) of 'Superduty refractories' is more than 33 which corresponds to a temperature of _____________ °C?
Correct answer: D. 1730
- A. 1520
- B. 1630
- C. 1670
- D. 1730
Explanation
A Seger cone number above 33 indicates a refractoriness exceeding roughly 1730°C. Therefore the matching temperature range is above 1730°C.
