摘要
氧枪喷头结构是影响转炉冶炼效果、控制金属喷溅的重要因素之一。本文根据氧枪管道压力损失的测定结果,对80t转炉的氧枪喷头参数进行了优化研究。水模试验结果表明,新喷头对熔池的冲击深度和冲击面积均优于原喷头。使用新喷头在转炉冶炼效果表明,枪龄比原喷头提高了256%,且终点脱硫脱磷率均有一定的提升。
The structure of oxygen lance nozzle is one of the important factors influencing the metallurgical effect and controlling metal splash.In this paper,based on the measured results of the pressure drop of oxygen lance pipe,we studied on optimization of the parameters of the oxygen lance nozzles of 80 t BOF.Water model experiment results show,by using the new oxygen lance nozzle,the impact depth of metal bath and the impact area of metal bath are both better than the original.By using the new oxygen lance nozzle,the production practice showed,the lance life improves 256%,and the end point of desulphurization rate and dephosphorization rate have been enhanced.
