并罐式无钟布料器落点计算分析
|
摘要
为了研究并罐无钟布料器炉料落点,以4150 m~3实际高炉参数为基础,基于炉料运动过程建立模型。通过模型分析得到料流宽度增加1m,则溜槽最大倾角减小2.5°。料线高差增加1m,落点半径增加0.83m。溜槽长度增加1m,落点半径增加0.83m。通过与1∶1布料实验数据作对比,得到平均误差百分比为2.93%,验证了模型的准确性,为优化布料设计提供理论依据。
In order to study the burden falling point of the two parallel hoppers with bell-less top,based on the bell-free top of 4150 m~3 blast furnace,a mathematical model was built to analyse the burden movement process. The distribution of the falling point is researched,with increasing the burden width by 1 m,the chute maximum angle is reduced by 2. 5°. With increasing the stock line height distance by 1 m,the drop radius is increased by 0. 83 m. With increasing the length of chute by 1 m,the drop radius is increased by 0. 83 m. By comparing the experimental data with 1∶ 1 burden distribution process,the average error percentage is 2. 93%,which verifies the accuracy of the model and provides the theoretical basis for optimizing the fabric design.
