通过凌钢竖炉炉型改造前、后的情况对比,分析了烘干床面积与焙烧带面积的相关性;决定竖炉生产能力的因素;竖炉热工制度与炉型的关系。炉型各部尺寸的配合是否合理,最佳热工制度如何选定,其关键是看焙烧能力与烘干能力是否同步。 According to the comparison between before and after transformation of furnace furnace in Linggang, the correlation between the area of ​​drying bed and the area of ​​baking zone was analyzed. The factors that determine the productivity of shaft furnace and the relationship between the furnace system and furnace type were analyzed. Furnace size with the cooperation of the ministries is reasonable, the best choice of thermal system, the key is to see whether the roasting capacity and drying capacity are synchronized.
