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1．6m^3／（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25kWh／t，冶炼成本下降100元／t以上。[著者文摘]

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 furnace can reach up to 1.6 m^3/（ t · min） by using arc furnace wall USTB coherent oxygen supply technology. The practice effect indicated that the coherent oxygen supply technology could meet the requirement of high hot metal charging 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.[著者文摘]
