is the abbreviation for “not available” due to the elimination of open hearth, bnegative value is due to the negative energy steel-making technology, cand the great decline of process energy consumption of EAF is because that China has adjusted the standard coal coefficient of electricity from 0.404 kgce/kWh to 0.1229 kgce/kWh since 2006.
