低碳炼铁、节能降耗及降低成本都要求降低燃料比。这是当前高炉炼铁发展的必然趋势,也是长远的目标。实践早就证明,高产与降低燃料比存在矛盾,在钢铁短缺的时候强調强化还情有可原。当今不管是管理、生产、操作还是设计都应该用新的尺度来衡量所有技术措施的合理性。本文从降低燃料比为中心,对几个热点问题进行了讨论。 Low-carbon iron, energy saving and lower costs are required to reduce the fuel ratio. This is the inevitable trend of the current development of blast furnace ironmaking, but also the long-term goal. Practice has long proved that there is a contradiction between high yield and fuel reduction, and it is also plausible that emphasis should be placed on strengthening in the absence of steel. Today, whether it is management, production, operation or design, a new measure should be used to measure the reasonableness of all technical measures. This article focuses on reducing fuel ratio and discusses several hot issues.
