Tundish model

Fluid flow in the tundish has been investigated thoroughly. Several investigators including the present author have studied behavior of steel melt flowing in a single and multi strand tundish. In the original installation of the continuous casting machine, role of tundish was to act as a distributor of molten steel to different molds at constant speed. It has soon been realized that tundish can be used to float inclusions or to add alloying elements during the process of continuous casting. To full fill the above objective it became necessary to modify the existing tundish design.  Physical model of a tundish of single and multi strand casters has been designed by several investigators to study the fliuid flow behavior in the tundish

Design a physical model of a single strand slab caster tundish. The base length of the tundish is 3450mm, width 1100mm and height 1320mm. Tundish is rectangular shaped with slopping walls. Submerged ladle shroud diameter is 78mm. Volumetric flow rate of steel in the tundish is . Scale of physical model .

Now we have to design a tundish. One must keep in mind the future modifications that would be required. We may require to modify the flow of fluid in the tundish. We have to make previsions to insert flow modifiers like dam and weir etc.

The dimensions of the model tundish are . The tundish is rectangular in cross section with slopping side walls. The tundish may be provided with the grooves to insert dams and weirs etc.  A submerged stream is poured from the model ladle to the tundish.

Physical model of the tundish is designed to study the fluid flow behavior in terms of flow pattern and residence time distribution.
