OPTIMIZATION OF TUNDISH EQUIPMENT
Abstract
This paper compares residence times of non equipped tundish and tundish equipped with Turbostop and weirs at three different casting speed. Set of measurements in this paper was performed in laboratory simulated flow processes (LSSP). Water model is assembled at scale 1:3 to original. Measurements were evaluated by graphical measuring of water conductivity variation at tundish inlet and outlet by adding potassium chloride into tundish inlet and visually where KMnO4 was used as indicator.
Within the frame of tundish equipment optimization three different variants were compared with support of Turbostop and weirs in two different distances from impact area.
