Several years ago, in response to the trends in continuous casting technology, Paul Wurth undertook a program to develop and improve casting technology for high quality billet and bloom production.The goal of the program was to simplify the casting machine and design the equipment to be able to produce high quality billets at higher casting speeds. The approach was three-fold: first, design a new oscillation system with more control and flexibility; second, improve the spray conditions to support the higher casting speeds; and third, implement longer mold designs. © 2000 Canadian Institute of Mining and Metallurgy.

Résumé Il y a plusieurs aneées, en résponse aux tendances de la technologie de coulée continue, Paul Wurth a entrepris un programme de développement et d'amélioration de la technologie de coulée pour la production de haute qualité de billette et de lingot. Le but du programme était de simplifier l'appareil de coulée et de concevoir de l'equipement permettant de produire des billettes de haute qualité à de plus grandes vitesses de coulee. L'approache comprenait trois parties; premieéement, concevoir un nouveau système d'oscillation avec plus de contrôle et de felxibilité, deuxiemement, ameliorer les conditions d'aspersion afin de supporter les plus grandes vitesses de coulée et, troisèmement, fabriquer des moules plus longs. © 2000 Canadian Institute of Mining and Metallurgy.
