Thermal -Mechanical Model of Solidifying Steel Shell Behavior and Its Applications in High Speed Continuous Casting of Billets
… to investigate three separate issues in high speed continuous casting: the minimum shell thickness to avoid breakouts, the maximum casting speed to avoid hot off-corner sub-surface cracks, and the optimal mold taper.

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 …

Transient thermo-fluid model of meniscus behavior and slag consumption in steel continuous casting
… to conduct a parametric study on the effect of casting speed, stroke, frequency, and modification ratio on slag consumption. Slag consumption per unit strand area increase with increase of stroke and modification ratio, and decreases with increase of casting speed while the relation with …

Argon Bubble Behavior in Slide-Gate Tundish Nozzles During Continuous Casting of Steel Slabs
… to reduce nozzle clogging in the continuous casting process. It also affects casting operation and product quality by changing the flow pattern in the nozzle and mold. The current work combines mathematical modeling and experiments to investigate the argon bubble behavior in slide-gate …

Inclusion behaviour in the liquid core during continuous casting.
… developed in the sump of a steel continuous casting machine and the influences these have on the behaviour of inclusions. An experimental method has been devised to simulate the behaviour of inclusions in the sump and to study the apportionment of the input flux of inclusions between the …

Numerical analysis of direct-chill casting of aluminum ingot
Direct chill (DC) semi-continuous casting is the most efficient way to produce large aluminum ingots. This process consists of three main stages; transient stage, steady-state stage, and post-drop stage. During transient stage, the ingot is subjected to rapid cooling rate and thus resulted in the …

Study of spray-cooling control for maintaining metallurgical length or surface temperature during speed drop for steel continuous casting
Continuous casting is an important engineering process through which nearly all of the steel is currently produced worldwide. Steel strand surface temperature and metallurgical length are two key processing variables requiring a proper real-time control to meet product quality and operational …

Argon bubble transport and capture in continuous casting with an external magnetic field using GPU-based large eddy simulations
Continuous casting produces over 95% of steel in the world today, hence even small improvements to this important industrial process can have large economic impact. In the continuous casting of steel process, argon gas is usually injected at the slide gate or stopper rod to prevent clogging, but …

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 …

Shape distortion and air gap formation during continuous casting.
… shell of steel solidifying in a continuously casting mould, to the shape distortion and the formation of an air gap. The work postulates that the behaviour of this shell can be analysed as that of a flexible structure formed by four elasto-perfectly plastic beams linked by rigid comers. This …
