摘要
以某厂210吨RH为原型,建立了模型与原型尺寸比为1:4的物理模型。本文综合考虑实验的准确性、经济性、效率和可行性等因素,探讨了RH水模实验测量混匀时间和循环流量的具体方法。确定了合理的示踪剂加入位置为真空室以及示踪剂最优加入量为每吨水427ml,提出了合理的测量混匀时间的位置为距钢包底50mm靠近钢包壁远离浸滞管的位置。
A water model of 1/4 linear scale for 210 t RH degasser has been established. This paper study the specific methods of measuring mixing time and circulation flow rate in RH water model experiment by the thinking of the accuracy the economy the efficiency and the feasibility of the experiment. The reasonable position of the tracer was determined as the vacuum chamber and the optimal amount of tracer added was 427 ml per ton of water. A reasonable measurement of the mixing time was made at a location 50 mm from the bottom of the ladle, near the ladle wall away from the dip tube.
