摘要: 研究了钢厂即将投产的120 t钢包底部最佳透气砖位置,在实验室以1:3建立钢包水模型进行模拟试验,得出最佳透气砖位置及吹气方式。实验表明,越靠近包壁的透气砖,其混匀效果越好,但对包壁的冲刷也越严重。在相同喷吹位置的情况下,双透气砖方案比单透气砖方案混匀效果好,且大角度(≥90°)的双透气砖方案比小角度双透气砖方案好。本实验的最佳吹气方案为离包底中心0.60R(半径)处,夹角为120°的双孔底吹气方式。

Abstract: The optimum gas permeable brick position in bottom of 120 t ladle being about to production at steel works has been studied. The established geometric similarity ratio 1: 3 water model for the ladle is simulated and tested in laboratory to get the optimum permeable brick position and gas blowing mode. Test results show that the gas permeable brick is nearer to ladle wall, the mixing effect is better but the ladle wall erosion is more serious. With same position condition the mixing effect by using double gas permeable bricks scheme is better than that by using single gas permeable brick scheme and the scheme of double gas permeable brick is with larger anger (290°) is better than that with small anger. The optimum gas blowing scheme in this test is bottom double gas mode with permeable brick at the distance from center of ladle bottom- 0. 60R (radius) and angle 120°.
