The European Commission, Directorate General XII, has recently published a report entitled "The influence of roll entry conditions on surface quality, solidification structure and dimensional control of direct cast strip produced from a twin roll casting machine". It is the final report for the project which aimed to determine the best processing conditions for high quality steel at a twin roll direct strip casting plant.

The report covers the researchers' findings on the inter-relationships which occur within a roll entry liquid metal pool and influence the surface quality, microstructure and dimensional tolerances of the final cast when twin roll casting technology is used. The project also aimed to develop technology for vacuum control of the feed rate of liquid metal to find the best conditions for manufacturing consistently high-quality steel.

The report covers the processes studied and the engineering enhancements supporting the trials programme. It also gives details of studies carried out on the products. These included surface evaluations and thickness measurements of the product, post-casting studies, and studies of silicon steel strip products.
