1. The cost competitiveness of electric furnace steelmaking is not strongSince 2000, the proportion of my country's electric furnace steel output has fallen from the highest 17.6% in 2003 to 6.1% in 2015, and the development speed is obviously lagging behind that of converter steelmaking. The bigges
