摘要

为研究210 t RH上升管吹气孔堵塞对循环流量的影响

进行了1:4水模型试验。结果表明

顺次堵吹气孔3个以上时

循环流量明显降低;堵塞吹气孔数量相同时

对称堵吹气孔对循环流量的减少小于顺次堵吹气孔

堵吹气孔3个和3个以下时可以正常生产;降低吹气孔的位置可以显著提高循环流量。

Abstract

In order to study the influence of nozzles blocking of a 210 t RH unit up-snorkel on circulation flow rate

the 1:4 water model test has been carried out. Results show that with numbers of blocking nozzles in sequence being more than 3

the circulation flow rate decreases obviously; as the number of blocking nozzles is same

the decrease of circulation flow rate with blocking nozales in symmetry is less than that with blocking nozzles in sequence; RH process could be normalcontinuous as the numbers of blocking nozzles are 3 or less than 3;and with lowing the location of nozzles the circulation flow rate increases markedlv.
