一、前言近年来,高炉容积日趋大型化,炼铁技术发展较快,表现在精料、喷吹、富氧、高风温等方面都有很大程度的变化和提高,这些都是以提高产量、降低焦比为中心而采取的措施。就高风温本身,它不仅能降低焦比节省能源,而且也能增加高炉的喷吹量。我国内燃热风炉目前风温水平在1100℃左右,个别热风炉在短时期内能达到1150℃,但是要长时间能把风温稳
I. Foreword In recent years, the capacity of the blast furnace has become increasingly large and the iron making technology has developed rapidly. The performance of the iron making technology has been greatly changed and enhanced in concentrate, injection, oxygen enrichment and high winds, all of which are based on the enhancement of Production, reduce coke ratio as the center of the measures taken. In the case of high temperatures alone, it not only reduces the coke ratio to save energy, but it also increases the blast volume. Domestic combustion stove current temperature level at about 1100 ℃, individual stoves can reach 1150 ℃ in a short period of time, but for a long time can the wind temperature stability
