9th ECCC European Continuous Casting Conference – ECCC 2017

Monolithic isostatically pressed ceramics for flow-control applications usually consist of 20-30wt% of carbon plus refractory components. The main role of the carbon is to create a thermal shock resistant microstructure in the ceramic body. One negative side effect is it’s relatively high thermal conductivity which can lead to temperature losses of the liquid metal on its transfer from...

We present an experimental study about the influence of magnetic stirring in the submerged entry nozzle (SEN) for continuous casting of round blooms performed at the mini-LIMMCAST facility at Helmholtz-Zentrum Dresden-Rossendorf (HZDR). The experimental setup consists of a round mould with an inner diameter of 80 mm made of acrylic glass, representing a mould used in industry. A magnetic...

In the recent study from the authors [1] a criterion is established for the near wall mesh treatment for simulating submerged entry nozzle (SEN) flows for the industrial applications. Fulfilling the criterion is found to crucial when it concerns a possible flow detachment (see Fig. 1) inside the continuous casting (CC) SEN. A numerical model, based on the RANS approach, matches the...

To improve the productivity of continuous casting, the adoption of thin slab caster is being steadily increased. Due to high speed casting of thin slab caster, the optimized deign for SEN becomes precondition for stable operation in casting. Design technology for SEN has been improved through fluid flow analysis and thermal stress analysis by computer simulation and water model...
