摘要
研究了喷头变形、喷头漏水和氧枪枪身粘钢对氧枪使用寿命的影响,并且对产生这3种因素的具体原因进行了分析。结果表明通过采取优化喷头相关参数,建立"低温低硅、中温中硅、高温高硅、低温高硅、高温低硅、高生铁块比和高铁水比"7种操作模式等措施,使得氧枪寿命提高了141炉,钢铁料消耗降低了4kg/t(钢),喷溅渣数量降低了3kg/t(钢),氧气消耗降低了1.9m3/t(钢),石灰消耗降低了5kg/t(钢),转炉脱磷率提高了8%,转炉脱硫率提高了4%。
In this paper,the effects of nozzle deformation,nozzle leaking and steel sticking of oxygen lance on the service life of oxygen lance have been investigated and the specific causes for the three factors have been analyzed.The results indicates that the service life of oxygen lance is increased by 141 furnace,by optimizing related parameters of the nozzle and establishing seven kinds of operation mode as followed：＂low temperature and low silicon＂ ＂medium temperature and medium silicon＂ ＂high temperature and high silicon＂ ＂low temperature and high silicon＂ ＂high temperature and low silicon＂ ＂high ratio of raw iron＂ and ＂high ratio of hot metal＂,The metal material consumption was reduced by 4 kg/t.The frequency of slag splashing was reduced by 3 kg/t.Oxygen consumption was decreased by 1.9 m3/t.The lime consumption was reduced by 5 kg/t.The dephosphorization rate of converter was increased by 8%.The desulphurization rate of converter was increased by 4%.
