Desirable "Micum Index" values of metallurgical coke are ___________________?
Correct answer: A. M40 > 78% and M10 < 10%
- A. M40 > 78% and M10 < 10%
- B. M40 > 4% and M10 10% and M10 98% and M10 < 2%
Explanation
Strong metallurgical coke should resist both impact and abrasion, represented by a high M40 value and a low M10 value. The usual desirable limits are M40 above 78% and M10 below 10%.
