Description
Clog formation within the submerged entry nozzle is highly detrimental to the fabrication of steel alloys during the continuous casting process. The growth of the clog is self-accelerating and leads to numerous issues in the manufacturing process, including reduced manufacturing speeds, changes to the steel solidification pattern and even the introduction of detached parts of the clog into the finished product. In this study we present a multi-scale approach to model the differing adhesion behaviour of various Non-Metallic-Inclusions (NMIs) and their influence on clog formation within the SEN. A macroscale transport model, developed in OpenFOAM is used to simulate the bulk transport of melt and particles, while a microscale model is used to simulate different adhesion behaviours of various NMI. This is combined with another microscale model to simulate the clog formation and growth, the presence of which, then effects the melt flow, in a positive feedback loop.
