Mathematical Simulation for the Effects of Flow Control Devices in a Six- strand Tundish in Continuous Casting of Steel Billet

The method of continuous casting of steel is now often used in the metallurgical industry, due to the increasing demand for the production of high – quality steel. An important device of continuous casting machine is the tundish, in which a stabilized steel flow has a crucial effect on the quality and efficiency conditions of the continuous casting process. In this study fluid flows in a six – ...

Evaluation of Heat Transfer Coefficients along the Secondary Cooling Zones in the Continuous Casting of Steel Billets

In the present work, heat transfer coefficients (h) along different cooling zones of a continuous caster billet machine were determined during casting of low and medium carbon steels. The effects of casting parameters, such as machine characteristics, the ingot dimension, mold, sprays zones, radiant cooling, melt composition and casting temperature were investigated and correlated with heat tra...
