摘要
分析了当前高炉炼铁技术面临的形势和挑战,提出了当代高炉炼铁技术的发展目标。阐述了高风温、富氧喷煤对高炉炼铁的意义和作用。重点分析和论述了实现高风温和高富氧大喷煤的关键技术。提高风温、提高富氧率、增加喷煤量是降低燃料消耗、节约生产成本和实现可持续发展的重要保障。在高风温、低燃料比冶炼条件下,当代高炉炼铁技术具有广阔的发展前景。
The present status and challenges of blast furnace ironmaking technology are analyzed, and the developing objectives of the contemporary BF ironmaking process are mentioned. The significance and function of high blast temperature and oxygen enriched-pulverized coal injection for BF ironmaking are described. The key technologies of high blast temperature and oxygen enriched-PCI are discussed and evaluated emphatically. Promoting blast temperature and improving oxygen enrichment ratio, as well as enhancing PCI rate are important guarantee for saving fuel consumption, reducing operation cost, and realizing sustainable development. There are broad developing prospects of contemporary BF process under the condition of high blast temperature and low fuel ratio in ironmaking technologies.
