| 摘 要： | 分析研究了热装铁水比对100t竖式电弧炉吨钢电耗、吨钢氧耗、冶炼周期和冶炼成本的影响以及对原材料、氧气供应、水冷条件、除尘能力等的要求。通过采用电弧炉炉壁USTB集束供氧技术,该电弧炉的供氧强度达到1.6 m3/(t·min)。实践表明,该集束供氧技术能满足高热装铁水比冶炼的要求,在相同热装铁水比下,冶炼电耗降低25 kWh/t,冶炼成本下降100元/t以上。

| Abstract: | The effect of hot metal charging rate on electric power and oxygen consumption per ton steel,tap to tap time and melting cost of an 100 t shaft arc furnace at Anyang Steel was analyzed and studied. The oxygen supply intensity for this arc fumace can reach up to1.6 m3/(t·min)by using arc fumace wall USTB coherent oxygen supply technology. The practice effect indicated that the coherent oxygen supply technology could meet the requirement of high hot metal char- ging rate melting,and under equal hot metal charging rate condition the smelting electric power consumption could reduced by 25 kWh/t and the smelting cost could decreased by 100 yuan/t. |
