这篇短文旨在评论生铁和粗钢生产所需能量的总额与形式.主要想给对炼钢能量需求情况了解不深的人而写,但对见识广博的人也会有所裨益.内容包括从原材料准备直到粗钢生产的所有工序. 首先论述高炉炼铁能量需求的发展,接着评述直接还原炼铁能量的需求.讨论了煤气竖炉和用煤的回转窑两种直接还原炼铁法.最后,对高炉/氧气顶吹转炉与直接还原炼铁/电弧炉两种炼钢生产流程的能量需求作了发展分析与比较.
This essay aims to comment on the total amount and form of energy required for the production of pig iron and crude steel, mainly for those who have little knowledge of the energy needs of the steelmaking plant, but also for those who are knowledgeable. From raw material preparation to crude steel production, the paper first discusses the development of blast furnace ironmaking energy demand, and then reviews the demand of direct reduction ironmaking energy.Two types of direct reduction ironmaking methods are discussed, including gas shaft furnace and rotary kiln using coal. Finally, the development and comparison of the energy requirements of blast furnace / oxygen top blown converter and direct reduction ironmaking / electric arc furnace are given.
