150t交流电弧炉炼钢高效化节电

Technological Research on High Efficiency and Electricity Saving of 150 t AC Electric Arc Furnace Steelmaking

采用了统计分析、物料衡算及能量衡算等研究方法,对天津钢管公司150t交流电弧炉炼钢高效节电技术进行了研究.三项单元技术研究针对特有的四元炉料结构,研究其对吨钢冶炼电耗的定量影响;使用4支炉壁氧枪和2支炉门氧枪及分时段供氧技术,保证了1.4 m^3/(min·t)的供氧强度,提高了氧气利用率;研究新的更大容量变压器的合理供电技术,保证了100 MW变压器炼钢安全、高效运行.在此基础上,按炼钢生产速率和能量需求进行有效综合研究,取得了高效、节电的显著效果.

In th/s article technology was researched on high efficiency and eleetricity saving in 150 t AC electric arc furnace(EAF) steelmaking process of Tianjin Steel Pipe Company.Some methods were used which were the statistical analysis,the material balance and the energy balance calculation in the research.It contains three unit techniques:for the influence on the specific electric consumption through studying the furnace charge structure,guaranteeing the oxygen supply intensity that was 1.4 m^3/(min·t)to raise ...
