为了提高炉缸中心的活跃程度,实验采用高炉二维冷态模型,对高炉炉身下部区域中心部位产生的焦炭粉末在下降过程和流入炉缸中心的情况进行了基本的探讨,得到了以下结论。 (1)炉缸中心煤气的空塔速度较小时,中心区域产生的焦炭粉末除移向回旋区外,由于炉缸小心斜面的浸透效果,一部分也流入炉缸中心的中间部位。 (2)炉缸中心煤气空塔速度较小时,炉缸
In order to improve the activity of the center of the hearth, a two-dimensional cold model of the blast furnace was used in the experiment. The coke powder produced in the central part of the lower part of the hearth of the blast furnace went down and the flow into the center of the hearth was basically discussed. . (1) When the superficial gas velocity of gas in the hearth is small, the coke powder generated in the central area moves to the center of the hearth as a result of the penetration effect of the bevel in the hearth. (2) hearth gas center tower when the air speed is small, the hearth
