针对涟钢100t钢包底吹氩搅拌过程中钢液喷溅所造成的钢液二次氧化以及对渣线砖区域包壁腐蚀严重的现象,在实验室以1:3建立钢包水模型进行模拟研究,考察其底吹透气元件的个数及布置方式、吹氩流量对搅拌效果和侧壁冲刷的影响.结果表明,透气元件越靠近包壁,搅拌效果越好,但对包壁冲刷越严重.在相同喷吹位置的情况下,采用双透气元件吹氩可以有效的减小钢液对包壁的冲刷,且搅拌效果也优于单透气元件.
Aiming at the secondary oxidation of molten steel caused by molten steel splashing in Lianyuan Steel 100t ladle bottom blowing argon stirring and the serious corrosion of the cladding wall in the slag line brick area, , The effect of blowing argon flow on the stirring effect and sidewall scouring was investigated, and the results showed that the closer the ventilation element was to the cladding wall, the better the stirring effect, but the more serious the wall erosion. In the case of the same injection position, the use of double ventilation components argon can effectively reduce the molten steel on the wall erosion, and the mixing effect is also better than the single breathable components.
