Formulation of Mold Level Control Model by Molten Steel Flow Analysis Method

This paper describes activities relating to mold level control in continuous casting process as case examples of our process control solution business, in which we clarify and evaluate the process phenomena and design the control system. Initially, a mold level control model has been formulated by fluid flow analysis technique that evaluates molten steel flow in the mold quantitatively. The model calculates the fluid flow and free surface in the mold by molten steel flow analysis method, while control system analysis is performed simultaneously. It enables realistic simulation of the mold level control system considering the fluid flow turbulence. As a consequence, mold level control in high-speed casting can be predicted and evaluated with high accuracy.
