RH下降管长度对钢包混匀时间影响的水模实验

Water model experiment of influence of RH down pipe length on ladle mixing time

以某炼钢厂210 t RH为原型,建立了模型与原型尺寸比为1:4的物理模型。采用示踪法测定了RH水模型不同下降管长度时,钢包模型内不同位置的电导率变化(RTD曲线)情况,计算了不同位置的混匀时间,分析了下降管长度对钢包内不同位置混匀情况的影响。

210 t RH in on steel plant is taken as prototype, the physical model with 1 ： 4 scale is established.By using trace method, the conductivity changes （RTD curves） in different locations within the ladle modelare measured with different down pipe length, the mixing time in different locations is calculated, and the in-fluence of down pipe length on mixing uniform situations in different locations of ladle is analyzed.
