| 摘 要： | 通过1:6水模型试验分析了顶枪吹气辅助扒渣过程中的驱渣动力学机制,试验研究了喷吹气体流量（10~30 L/min）,喷枪插入深度（90~270 mm）和位置（距边缘0~160mm）对扒渣效果的影响。结果表明,随着喷吹气体流量、顶吹喷枪插入深度的增大和喷枪插入位置至铁水罐后壁距离减少,驱渣效果显著改善,有利于铁水渣的扒除。工业应用试验结果表明,采用顶吹辅助扒渣工艺后,扒渣时间明显缩短,但铁损没有显著降低,须进一步优化工艺参数。

| Abstract: | The dynamic mechanisms about slag skim during top lance blowing gas skimming slag process are analyzed by 1 ：6 water model test, and the effect of blowing gas rate ( 10-30 L/min) , lance submerged depth (90-270 mm) and lance location ( distance from edge 0-160 mm) on slag skimming results has been tested and studied. Results show that with increasing blowing gas rate and top lance submerged depth and reducing the distance between the submerged location of lance and the hot metal ladle back wall, the results of slag skimming are obvious improvement , it is available to skim slag on hot metal. Commercial application pilot production results show that with using top-blowing auxiliary skimming slag process the slag skimming time is markedly reduced, but the iron loss is not obvious decrease, it needs to further optimize process parameters. |
