结合现代高炉生产实践,简要阐述了高炉铁口数量过多和铁口数量过少对高炉生产的不利影响,分析了每个铁口合适的昼夜通铁量,并计算了不同炉容高炉的铁口数量。认为,科学地选择铁口数量,对降低投资和运行成本,促进高炉长寿等方面都具有积极的意义;在目前高炉的操作水平及耐材质量等条件下,每个铁口的昼夜通铁量在4500~5500t是比较合适的。计算结果表明,对于4000m~3级以上高炉而言,选择3个铁口可以满足生产要求。
Combined with the practice of modern blast furnace production, the adverse effects of over-blasting and over-blasting on blast furnace production are briefly described. The suitable day-night throughput of each blast-furnace is analyzed. Number of mouths. It is considered that the scientific selection of the number of tapholes has a positive meaning in terms of reducing investment and operating costs and promoting the longevity of the blast furnace. Under the current operating conditions of the blast furnace and refractory quality, 4500 ~ 5500t is more appropriate. The calculation results show that, for the 4000m ~ 3 above blast furnace, the choice of three iron mouth to meet the production requirements.
