FOMTM – Application of fibre optical thermal monitoring at CC-billet and slab mould for improved process control and product quality

Initial situation:

  • The initial solidification of the molten steel is important for determining the quality of the cast product
  • Rim formation can have severe damaging impact on the surface of the solidifying strand
  • Currently no regular use of thermal mould monitoring for tube moulds for long product casting

Project targets:

  • Design of an fibre optic temperature sensor (FOTS)
  • Realisation and installation of pilot FOTS system
  • Industrial trials on the caster with pilot FOTS system and the developed analysing software
  • Data elaboration and rules, tuning of the system, industrial transferability, suggestion for standards

Innovative approaches:

  • Develop and operate a better control of initial solidification at meniscus level
  • Further develop fibre optical mould temperature sensors for multiple use
  • Operate the system under industrial practise at a billet and slab mould

Benefits for the industry:

  • Enhance surface quality of as-cast products
