乌克兰的克理沃罗冶金工厂160t转炉为了改善造渣和供氧的热工制度,于199O年应用我国鞍山热能研究院生产的单流道供氧、双层喷孔的氧枪喷头进行了生产试验。喷头的主喷孔为拉瓦尔型;副喷孔为直筒型,出口位于喷头的侧壁,呈椭圆形状。副喷孔氧气流量占总流量的11%。枪体结构考虑到改善喷头中心顶部冷却条件的要求。中国制造的试验喷头与克理沃罗冶金工厂原来使用的喷头主要技术参数列于表1。 相似文献

In order to meet the requirement of semi-steel making, the original nozzle was optimized by Vanadium-recoverying and Stee1-making Works of Pangang. And then every parameters of the oxygen lance were assessed according to industrial tests. Results show that, comparing with the original oxygen lance nozzle the new designed one has a better metallurgical effect, the average volume of oxygen and oxygen supply intensity were increased by 774m3/h and 0.19 m3/(t·min) respectively, oxygen consumption was reduced by 1.87m3/t, the blowing time was lowered by 56 seconds, a better dephosphorization effect was obtained by the new one. 相似文献
