Crystallisation Behaviour and Heat Transfer Phenomenon of Fluoride-free Mould Fluxes for Steel Continuous Casting
Mould fluxes provide indispensable functions for steel continuous casting, such as heat transfer control, lubrication, thermal insulation, inclusion entrapment, and oxidation prevention. Most of the commercial mould fluxes contain fluorides to ensure high steel quality, but they also bring about …

Investigation of meniscus region behavior and oscillation mark formation in steel continuous casting using a transient thermo-fluid model
In the continuous casting of steel, many complex phenomena in the meniscus region of the mold are responsible for the formation of oscillation marks. Oscillation marks are depressions found around the perimeter of continuously cast steel slabs, which if too large can lead to cracking in steel …

Correlation for measured mold heat flux and CON1D simulations for feasible operating conditions in thin-slab continuous casting
In steel continuous casting, controlling heat flux from top of the mold to caster exit is very essential for the production of high quality slabs in a safe environment. Cooling in steel continuous casting comprises primary cooling in mold followed by secondary cooling in spray cooling zone. In this …
