Abstract: A water model of 1/4 linear scale for 210t 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 427ml 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.

Key words: RH, water model, circulation flow rate, mixing time
