二次燃烧技术 (Because post-combustion technology is used, the EAF oxygen consumption increases from 26 Nm³/tonne to 42 Nm³/ tonne, and the corresponding power consumption is 315 kWh/tonne with a tap-to-tap time of 48 minutes. 由于采用了二次燃烧技术,该电弧炉用氧量由 26 Nm³/t 提高到 42 Nm³/t, 相应的用电量为315 kWh/t, 出钢到出钢时间为 48min。) |
