摘要/Abstract

摘要： 为解决铁水脱硫扒渣导致的铁损问题，通过对铁水脱硫渣物性及铁水扒损产生原因分析，采取水模冷态试验、500kg试验炉热态试验、十字型喷气枪设计及100t铁水罐工业生产试验，进行了铁水罐涌动式扒渣技术研究。研究结果表明：铁水罐倾动角度范围可满足2支喷枪垂直插入铁水，在铁水自下而上涌动力作用下铁水表面一半裸露，另一半顶渣呈“半圆形”淤积在扒渣口便于扒渣；对于100t铁水罐涌动式扒渣与常规扒渣方式相比，实现扒渣时间从11min缩短到7min，铁损从5.89t/罐减少到2.97t/罐，且不需要添加聚渣剂。

Abstract: In order to solve hot metal loss of skimming after desulphurization, the properties of desulphurization slag and the causes of hot metal loss during slag skimming were analyzed. The feasibility of hot metal gush skimming technology was researched, through water model experiment, thermal state experiment in 500kg top-bottom combined blowing furnace, experiments of cross gas injection gun design and industrial production test in 100t hot metal ladle. It was concluded that the range of hot metal ladle tilting angle range could satisfy two ejection guns vertically inserting into the hot metal; the surface of hot metal was half naked and the other half was covered by "semicircle" desulphurization slag which accumulated at the skimming mouth for skimming easily, with the action of gush power of hot metal bottom-up. Compared with conventional skimming of 100t hot metal ladle, gush skimming time was shortened from 11min to 7min, and hot metal loss was reduced from 5.89t to 2.97t per ladle with no additional slag-conglomerating agent.

Key words: hot metal ladle, skimming, desulphurizing, slag-conglomeration agent
