9th ECCC European Continuous Casting Conference – ECCC 2017

In the current work, an one-quarter scale water model was established to investigate the effect of bubbles and slags on the fluid flow in a slab continuous casting mold. The variation of the profile of the top surface and the critical condition for the entrainment of slags were studied using a high-speed camera. A Particle Image Velocimetry (PIV) was used to measure the fluid flow velocity and...

POSCO CEM® process can continuously produce coils without cutting before the finishing mill. Material balance with high throughput between the casting and rolling is essential to achieve this process. Throughput of CEM® has boasted a world-class level in the casting area. This was achieved with a high-speed casting technology and increased slab thickness up to 100 mm. Recently, many steel...

Slag entrainment is a challenging problem to control during continuous casting process. From fluid dynamics viewpoint, it mainly occurs due to (I) the instability of the fluids interfaces at the top of the mold and (II) vortex formation around the sub-merged entry nozzle (SEN). Both mechanisms are complex phenomena involving surface instability, vortex interactions with the metal-slag-air...

Variation across different length scales of phase evolution during solidification of steel define the final properties of the cast slab. Various multi-phase models by Ludwig et al [1] and Beckerman [2] for modelling of columnar / equiaxed solidification microstructures in alloys exist in literature. In today’s world of high quality steel, understanding the dependence of the...

In continuous casting of ferritic stainless steel electromagnetic stirring (EMS) is a common approach to generate an equiaxed crystal zone as large as possible. The layout of the electromagnetic device directly affects the intended solidification structure in the strand. In order to predict this influence, SMS group has developed a numerical model to simulate the interaction between flow...
