Abstract
The quality of continuous casting steel products depends on the solidification of the shell, during which marks or even cracks can develop. Powder lubricant are commonly used in order to reduce superficial damage risks: however, no consolidated theories are available to explain exactly their behaviour and, subsequently, guarantee an optimized casting procedure. The aim of the present research was to define a first model able to simulate the lubricant powder behaviour during the continuous casting of steel, in order to study and predict the fluid-dynamics parameters (as pressure and velocity fields) during the oscillation cycle.File in questo prodotto:
