Abstract:

The present study on hearth drainage phenomena was conducted by setting up a 1:10 scaled down three-dimensional physical model of G blast furnace hearth, Tata Steel. The novelty of this study is the use of thermocole balls which do not get wetted by liquid and thus simulate hearth conditions correctly. The effect of variables, such as blast pressure, taphole length, taphole diameter, taphole angle and initial liquid height in the blast furnace hearth on residual ratio of the liquid in water model has been studied.

Keywords: INITIAL LIQUID HEIGHT; TAPHOLE DIAMETER; TAPHOLE ANGLE; RESIDUAL RATIO; THERMOCOLE BALLS; HEARTH DRAINAGE; PRESSURE; TAPHOLE LENGTH
