Which of the following consumes the maximum tonnage of refractories annually in an integrated steel plant ?
Correct answer: C. L.D. converter
- A. Soaking pits
- B. Reheating furnace
- C. L.D. converter
- D. Rotary lime kiln
Explanation
The LD converter consumes a very large tonnage of refractory because its working lining is exposed directly to molten steel, oxygen blowing, chemical attack, and repeated thermal cycling. Its lining therefore requires frequent renewal.
