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.
