高炉炼铁能耗约占钢铁生产总能耗的50%,可见高炉节能对降低钢铁生产能耗具有举足轻重的地位,对发展国民经济具有十分重要的意义。本文就与高炉节能有关的燃料结构和焦炭质量问题谈几点看法。一、高炉合理燃料结构高炉节能,首先应确立高炉的合理燃料结构。即根据国家和地区的能源条件,以适当的燃料品种和方式,提供高炉冶炼所需之能源,达到能源的合理利用和最佳节省。随着焦煤资源的减少,节焦成了高炉冶炼最重要的问题。为此,六十年代以来普遍实行了从风口喷吹辅助燃料的技术,建立了
Blast furnace ironmaking energy consumption accounts for about 50% of the total steel production, showing that blast furnace energy saving plays a decisive role in reducing the energy consumption of steel production and is of great significance to the development of the national economy. This article on the blast furnace energy-related fuel structure and quality of coke talk about the views. First, the blast furnace reasonable fuel structure blast furnace energy saving, first of all should establish a reasonable fuel structure of the blast furnace. That is, according to the national and regional energy conditions, with the appropriate fuel varieties and ways to provide the necessary energy for blast furnace smelting, to achieve the rational use of energy and the best savings. With the reduction of coking coal resources, festival coke became the most important issue in blast furnace smelting. For this reason, the technology of blowing auxiliary fuel from tuyere has been widely practiced since the 1960s,
