摘要
通过国内外历年钢铁产量、综合能耗和轧钢工序能耗的变化,阐明轧钢技术进步。结合实例采用分类比较分析方法比较了不同品种轧钢系统的能耗结构,指出轧钢系统的节能应以加热炉节能为重点。在分析蓄热燃烧、涂料、步进炉、汽化冷却、热装热送、变频调速和轧钢自动化等技术基础上,结合首钢近年结构调整的实践,阐述了首钢不同地区轧钢系统节能技术应用状况和现存问题,指出了今后首钢轧钢系统的节能方向和对策。
With historical changes of steel output,total steel energy consumption and steel rolling energy consumption at home and abroad,steel rolling technology progress is il-lustrated.By sorted and compared methods with example,energy consumption structure of different varieties in the steel rolling system is analyzed.The analysis results show that ener-gy saving of the steel rolling system should be focused on energy saving of heating furnace.On the basis of analysis of the technology such as regenerative combustion,coating,walking-beam type furnace,vapourization cooling,hot loading and hot feeding,frequency conversion speed control and automation of steel rolling,in the light of the practice of structure adjust-ing in Shougang in recent years,application of energy-saving technology and existing prob-lems in the steel rolling system in different districts is expanded,the energy-saving trend and countermeasures of this system in the future is pointed out.
