我国电炉钢生产现状及发展前景

我国电炉钢产量逐年上升,2007年已接近5 000万t,同时电弧炉容量趋向大型化,2007年≥50 t电弧炉产能约占电炉钢总产能的83.5%,电耗接近300 kWh/t,冶炼周期≤60 min,平均电极消耗2.43 kg/t,但炉料结构、生产钢种、节能环保等方面的技术开发仍需加大力度,未来我国电弧炉流程仍有很大发展空间。

Present Status and Future Development of Domestic Electric Arc Steel Production

The output of domestic arc furnace steel increased year by year which was near to 50 million ton in 2007. The number of large electric arc furnace increased obviously,in 2007 the output of ≥ 50 t electric arc furnaces was about 83.5% of total electric arc steel,electric consumption decreased near to 300 kWh/t with tap-to-tap time ≤ 60 min and average electrode consumption 2.43 kg/t,but the processes related to charging,steel grade,energy saving and environmental protection need to be promoted. The domestic electric arc steelmaking process is forging ahead.
