摘要
以某钢厂250 t钢包为研究对象,通过水模型对现场生产过程进行模拟,研究钢包底吹气位置、吹气孔个数以及吹气量大小对钢水搅拌效果的影响。结果表明:单孔底吹氩,吹孔距钢包底部中心0.61R(R为钢包底部半径)时钢水混匀时间最短;双孔喷吹对称分布的钢水混匀时间比单孔喷吹的钢水混匀时间短,搅拌效果优;当双孔喷嘴对称分布的尺寸为0.61R时,钢水混匀时间最短、死区体积最小,且双孔喷嘴间距由0.37R增至0.61R时钢水混匀时间明显减少。
Taking 250t ladle of a steel plant as the object of study,through water model experiment of field production process simulation,the bottom air element size and arrangement of the influence of the mixing were studied.Results show that the nozzle location distance from the center of ladle bottom for single nozzle blowing is 0.61R (R is the ladle bottom radius),molten steel blending time is the shortest; the molten steel blending time with double nozzle blowing is shorter than that with single nozzle blowing,and stirring effect is better than that of single nozzle blowing,and as distance between double nozzle for double nozzle blowing increase from 0.37R to 0.61R,the molten steel blending time obviously decreases.
