Magnesite bricks are used in those parts of furnaces, which are __________________?
Correct answer: B. Required to resist corrosive basic slag
- A. Subjected to temperature fluctuation
- B. Required to resist corrosive basic slag
- C. Subjected to high load
- D. None of these
Explanation
Magnesite is a basic refractory and resists attack by corrosive basic slags. Temperature fluctuation and load resistance are important properties, but they do not specifically identify magnesite bricks.
