高炉无料钟炉顶布料器的冷却分析

Analysis on the Cooling for the Distributor of the Bell-Less BF Top

首钢一号高炉无料钟炉顶布料器是水冷、氮气密封的结构,对影响布料器冷却的各主要参数进行了分析,得出各个参数对布料器齿轮箱内温度的影响程度,在此基础上提出了一种旋转圆筒结构的改进方案,此方案可大幅度降低布料器内的温度,并可大量节省冷却水用量。

The distributor of the Bell-less Top of No.1 BF at Shoudu Iron and Steel Co.is an equipment cooled with water and sealed with nitrogen.From the analysis on the main factors which affect the temperature of the distributor,the rank of these factors is resulted.Based on the analysis a new type of a revolving cylinder is developed.This new one can reduce the inside temperature of the distributor and the amount of the cooling water largely.
