对太钢球团矿比例增加后对高炉压差的影响及应对措施进行了分析总结。认为压差升高的主要原因是高炉块状带空隙率ε下降,及软熔带位置上移和宽度增加。并提出了应对措施,一方面,通过烧结矿球团矿混装、调整装料制度和布料角度及混加焦丁等方式改善透气性;另一方面,改善球团矿质量。
The impact of the increase of the proportion of Taiyuan Pellet Mine on blast furnace pressure and the countermeasures were analyzed and summarized. It is considered that the main reason for the increase of pressure difference is that the porosity ε of the blast furnace bulkhead decreases and the position of the reflow ribbon moves upward and the width increases. And put forward the countermeasures. On the one hand, through the mixing of sinter pellets, adjusting the loading system and the fabric angle and mixing coke Ding and other ways to improve the permeability; the other hand, to improve pellet quality.
