The aim of the project was the construction and testing of a vacuum tundish system that can be installed and operated on slab machines of varying designs and with differing operating practices. Vacuum tundish casting offers the potential to improve the quality, yield and consistency of the continuous cast product, particularly during periods of transient casting.

This project report traces the progress of the work from initial trials using a first production prototype on the slab caster of Corus Scunthorpe Works to detailed design review and development work, including both pilot plant and production trials aimed at producing an improved vacuum tundish system capable of routine production operation. Major design improvements included upgrading of the vacuum system, provision of a dedicated preheat unit, optimisation of control loops and adaptation to operate with a sliding gate tube changer that helped to improve start of cast control. A new vacuum tundish was constructed for slab casting trials at Corus Strip Products, UK, Port Talbot Works incorporating these aspects. The work culminated in use of the system in a twin ladle production cast.

The final design is more robust and production oriented, although further simplification of operating characteristics would be desirable. Excellent control of mould level variability and steel surface quality has been demonstrated, although as yet there is no improvement in steel cleanness, which may be related to design compromises imposed by the need to retrofit the system into an existing tundish/SES geometry.
