摘要： 采用数值模拟方法考察了钢包底吹位置对侧底复吹RH装置内流体流动及循环流量的影响.计算结果表明:在钢包底吹条件下,当底吹位置和钢包中心连线与浸渍管中心连线夹角一定时,随着底吹位置至钢包中心距离的增大,循环流量先增大后减小;当底吹位置至钢包中心距离一定时,循环流量随夹角的增大而减小;与现有RH吹氩方式相比,当采用侧底复吹且钢包底吹气量保持在200 L/min时,循环流量可提高25%以上;当关闭上升管侧吹且仅采取钢包底吹时,与现有RH吹氩方式相比,循环流量可提高60%~100%.

Abstract: The numerical simulation method was employed to investigate the fluid flow and the effect of bottom-blowing location on the circulation flow rate in RH with side-bottom blowing. The numerical results indicated that for RH with bottom blowing, when the included angle is constant between the two lines connecting the bottom-blowing location with ladle center and connecting two snorkels, the circulation flow rate increases firstly and then decreases with the increasing distance between the bottom-blowing location and ladle center. When the distance between the bottom-blowing location and ladle center is constant, the circulation flow rate decreases with the increasing included angle. When the bottom-blowing gas flow rate is equal to 200 L/min, the circulation flow rate in RH with side-bottom blowing is up more than 25 percent. When the side-blowing gas flow rate is equal to zero, the circulation flow rate is 60%~100% greater than that in traditional RH.
