High alumina refractories are used in the ___________________?
Correct answer: D. All A., B. and C.
- A. Dome of blast furnace stoves
- B. Electric arc furnace roof
- C. Glass melting furnaces
- D. All A., B. and C.
Explanation
High-alumina refractories withstand high temperatures and chemical attack, making them suitable for blast-furnace-stove domes, electric-arc-furnace roofs, and glass-melting furnaces. Thus all three applications are valid.
