通过对铁浴式熔融还原炉的水力学模拟,研究了双排侧枪的侧吹角度、插入深度、侧吹流量以及侧吹位置对熔融还原炉内混匀时间的影响.改变上排侧吹实验的结果表明,熔池内的混匀时间随着侧吹角度的增加呈增加的趋势,随插入深度和喷吹流量的增加呈减小的趋势.改变下排侧吹实验的结果表明,熔池内的混匀时间随着侧吹角度和插入深度的增加呈减小趋势,随着喷吹流量的增加呈减小的趋势.通过比较混匀时间和喷溅量的大小,得到本实验条件下最佳的实验参数:在熔融还原炉的氧化区,即上排侧枪参数为插入深度50mm、与水平方向角度15°、流量9m3/h、侧吹在油层中的位置为1/3处最佳;在熔融还原炉的还原区,即下排侧枪参数为插入深度130mm、与水平方向的角度45°、流量9m3/h最佳.
Through the hydraulic simulation of the iron-bath smelting reduction furnace, the effects of side blowing angle, insertion depth, side blow flow and side blowing position on the mixing time in the smelting reduction furnace were studied. The experimental results show that the mixing time in the molten pool tends to increase with the increase of the side blowing angle, and tends to decrease with the insertion depth and the increase of the injection flow rate. The mixing time decreases with the increase of side blowing angle and insertion depth, and decreases with the increase of injection flow rate.By comparing the mixing time and the amount of splashes, Good experimental parameters: In the smelting reduction furnace oxidation zone, namely the upper row side gun parameters for the insertion depth of 50mm, and the horizontal angle of 15 °, the flow rate of 9m3 / h, side blowing in the reservoir position of 1/3 the best In the reduction zone of the smelting reduction furnace, the parameters of the lower row side guns are the insertion depth of 130 mm, the angle of 45 degrees with the horizontal direction, and the flow rate of 9 m 3 / h is the best.
