中文摘要: 针对4种不同的氧枪喷口结构进行了冷态试验研究，采用高速相机获得了不同喷口下的炉内气泡形态，采用电导率法测试了不同喷口下炉内流体的混合状况。试验结果表明，在相同的气体流量下，不同的气体喷口时炉内气泡的形态十分相似，当采用结构最复杂的喷口时，炉内的混合状态是最好的，结构最简单的喷口混合效果最差，其最小响应时间较最复杂喷口增加约11%，均混时间增加约4.7%。
Abstract:Four different nozzle structures of oxygen lance were studied by cold state experiment. Bubble morphology of different nozzle was obtained by high-speed camera, and mixing state of fluid in furnace under different nozzle was measured by conductivity method. The experimental results show that with the same gas flow rate, shape of bubbles in furnace is very similar with different gas nozzles. When nozzle with the most complex structure is used, mixing state in furnace is the best, and mixing effect of nozzle with the simplest structure is the worst. The minimum response time rises by about 11% and mixing time rises by 4.7% compared with the most complex nozzle.
