1. Introduction
Continuous casting is a casting process that is used in the manufacturing industry to produce molten steel at the temperature of 1,600OC and converted into particular size of slabs. This modern casting process is used in many steel manufactures as it has superior quality of castings, less loss of material, cost reduction and high productivity rate over the cast ingot production [1].
The continuous slab casting is started by adding and mixture the basic raw materials such as steels, silicon, magnesium and other basic materials of steelmaking in the furnace. The steel has low carbon contained, which is below 2% of carbon in the steel. The process of continuous slab casting process begins with melting and mixing the raw materials in the furnace. The molten steel in the ladle is tapped out from the bottom of the ladle into the intermediate container called as tundish by gravitational force, which helps the filling the mold along the continuous steel casting. Additionally, the continuous slab casting process is required a large space for the casting operation due to the tundish alone is located approximately 250m above the ground level and it can hold several tones of steel. The roles of the tundish are to supply a certain constant amount of the ...

Mathematical model predicts the heat and mass transfer in numerical framework for both transports phenomena of relevance to the industry continuous casting tundish system. Additionally, it has an excellent agreement outlet temperature respond the step input temperatures in the inlet stream of water in the tundish model. The simulations of 8x8 grid and 16x16 grid are applied to obtain significant difference between the TAV maps in which both grids are computed by software represent the specific flow of the fluid in the model and the steel caster as the actual size system. Therefore, the physical and mathematical modeling is used as a guidance to build a model before the prototype is constructed in terms of calculation, measurement and determination of specific fluid flow, heat and mass transfer in the water model.
