【摘要】 在相似原理的基础上,对天津钢管公司150t钢包精炼吹氩过程进行了水模拟实验(模型、原型几何比例为1:4).实验发现,原型钢包吹氩位置不尽合理,透气砖顶面面积偏小,吹氩流量偏大.通过对以上三指标的优化,确定合理的吹氩工艺参数为:将吹氩孔位置由原来的距钢包底中心分别为0.555R和0.634R移动到1/3R处,将透气砖顶面直径由原来的16mm扩大到35mm,吹氩流量减少到0.44m3-h-1.水模拟实验为原型钢包的工艺改进提供了依据.更多还原

【Abstract】 Based on the similar principle, water modeling experiment was carried out for the 150 t ladle furnace at Tianjin Pipe Corporation Ltd. (the geometry ratio is 1:4 between the model and prototype). It was found that the holes’ positions weren’t rational completely, porous brick was small, and gas flow rate was a little large. The rational argon blowing process is determined by optimizing experiments: the holes are moved to the position of 1/3R, the top diameter of porous brick is increased to 35 mm from 16 mm, and the gas flux is con-trolled to 0.44m3-h-1. The results provide references for the improvement of actual ladle.更多还原
