9th ECCC European Continuous Casting Conference – ECCC 2017

The application of magnetohydrodynamics in the continuous casting of steel enables improved control of the quality of the strand. The most common applications are electromagnetic braking (EMBR) and electromagnetic stirring (EMS). The former slows the flow by applying a static magnetic field and thus improves the steel flow pattern, reduces the velocity and the turbulence of the flow, increases...

Coupled thermal and mechanical model of continuous casting of thin slabs produced at OMK CSP was further developed. The model is constructed in the ANSYS Mechanical APDL software. For the tapered funnel mold, thermal 3D and structural 2D task was formulated and solved. For the secondary cooling zone, both thermal and structural problems were set as 2D models. The model is shown to represent...

These days the combination and utilization of the advanced numerical simulation techniques with the regulation algorithms is become the common standard in the industry production. In this paper the 3D macro solidification model for continuous casting process and original fuzzy logic regulator is described. The regulator was created in the focus on surface slab quality improvement. The macro...

Fully coupled thermo-mechanical finite element models were developed, also casting and soft reduction tests were carried out in an industry casting machine, to investigate the formation mechanism of one kind of typical inter-dendritic crack around triangular zone in slab casting process, applying soft reduction technology. The effect of soft reduction amount distribution design combined with...

Hot tearing is a regular defect that affects slab internal soundness. Hot tears form at the end of solidification, typically between 0.8 and 1 solid fraction, when steel exhibits low ductility but can be subjected to stresses which generate deformation. Excessive deformation will then open the dendritic structure and lead to cracks. New steel grades which are currently under development are...
