SEN design optimisation for high-speed thin slab casting

The design of submerged entry nozzles (SENs), particularly for thin slab caster funnel-type moulds,
is critical for controlling steel flow turbulence in order to avoid mould flux entrapment and
meniscus instability, and promote even heat transfer and steady flow conditions. Use of water
modeling and mathematical modeling techniques have helped optimize SEN design, resulting in
successful plant trials.
