Controlling the flow of steel from the tundish to the mould is very important for Conventional Slab Casters. It strongly contributes to the ability to produce the optimum steel quality with the maximum caster safety.

Achieving the highest steel quality and minimizing production downgrades or stops requires:

  • a precise and reliable control of the molten steel that guarantees a stable, level meniscus
  • an optimized introduction and distribution of steel in the mould
  • an appropriate formulation and consistent distribution of mould flux

Vesuvius brings its skills and experience to develop and service cutting edge solutions that maximize production quality and throughput with the highest level of safety. The integration of Avemis, Sert Metal and Metallurgica enlarged the Vesuvius portfolio and experience in this field.
