针对永通公司竖炉烘干气流分布不合理,由导风墙引入的冷却风流量不够,导致冷却风上行流入焙烧带,以及烘床梁篦条堵塞、变形等问题进行了分析,提出了相应的改进措施并予以实施。改造后,炉内气流分布得到优化,生球干燥速度加快,干燥效果好,球团矿产质量均得到提高。 In view of the unreasonable distribution of dry airflow in the shaft furnace of Yongtong Company and the insufficient cooling air flow introduced by the wind guide wall, the cooling wind flows upward into the roasting belt and the blockage and deformation of the grate bar in the bake bed are analyzed. Correspondingly, Improvement measures and implemented. After the transformation, the airflow distribution in the furnace is optimized, the drying speed of the green ball is accelerated, the drying effect is good, and the quality of the pellet mineral is improved.
