Resistance to slag attack of a refractory _____________________?
Correct answer: D. All A., B. and C.
- A. Depends on the nature of slag & refractory
- B. Decreases at higher temperature
- C. Decreases, if defective joints & cracks exist in the refractory
- D. All A., B. and C.
Explanation
Slag corrosion depends on chemical compatibility between the slag and refractory, and higher temperature generally accelerates attack. Cracks and defective joints also allow slag penetration, so all three statements are valid.
