前言目前国内外炼铁高炉趋向大型化、高生产率方向发展,高炉工作者在实践中认识到了从有限的炉缸及时排出大量渣铁的重要性。若出渣出铁不好直接影响炉况稳定,限制生产率的提高,不利于降低焦比,甚至造成事故,是日常生产中的麻烦问题。为此本 Preface At present, domestic and foreign ironmaking blast furnaces tend to be large-scale and high-productivity oriented. Blast furnace workers have realized in practice that the importance of timely discharge of large quantities of iron and steel slag from a limited hearth. If the poor slag output directly affect the stability of the furnace, limiting productivity increases, is not conducive to reducing the coke ratio, and even cause accidents, is the trouble in daily production. For this
