Chrome magnesite bricks are_________________?
Correct answer: C. Having higher RUL than silica bricks
- A. Acidic in nature
- B. Neutral in nature
- C. Having higher RUL than silica bricks
- D. Made by mixing 30% Chromite and 70% Periclase
Explanation
Chrome-magnesite bricks have a high resistance to softening under load, or RUL, and therefore outperform silica bricks in many high-temperature furnace zones. The stated composition using periclase is not the standard way to define all chrome-magnesite bricks, so option c is the reliable statement.
