Pyrometric cone equivalent (PCE) of a refractory is the measure of its_________________?
Correct answer: B. Fusion point
- A. Spalling resistance
- B. Fusion point
- C. Resistance to slag penetration
- D. Resistance to carbon monoxide attack
Explanation
PCE indicates the temperature at which a refractory cone softens and bends under its own weight, so it is used as an empirical measure of refractoriness or fusion temperature. It does not directly measure spalling or slag resistance.
