Assessment of long product defects

Ziel

The objectives of the proposed research can be summarised as follows: - enhancement of the hot deformation behaviour of CC semis through a thermal treatment combining "on-line" cooling at the caster below the critical point and a subsequent self-reheating of the cast strand;
- improvements to the surface quality of rolled products through the use of billets with unusually large corner radii (up to 1/3rd of the cast size); - provision of a computer-based system which will enable the rolling history of any defect found in a long product to be determined. The system will initially be developed with reference to billets, and possibly extended to other long products at a later stage. Consideration will be given initially to rolling operations but the intention is to extend the system upstream to cover reheating, and downstream to include finishing operations.
The ways and means of achieving the objectives involve model development, plant trials in the continuous casting and mill areas, and product investigation. The programme for model development includes the formulation of Finite Element Models and their validation against plant data. Information from the models will then be incorporated in a database. Plant trials are to include innovative casting and rolling of the resulting product.
