Various metallurgical issues negatively affect the current Level 2 model and cause significant model errors which cannot be removed by adaptive learning. Wide application of metallurgical processes (e.g., controlled rolling) calls for metallurgical principles in Level 2 model. The next-generation Level 2 should include a hybrid system by combining a full-range of metallurgical models with intelligent learning. The new model would also improve the pass schedule in controlled rolling. The revealed metallurgical issues, the general concepts of the next-generation Level 2 system, and the related metallurgical models in rolling, reheating and accelerated-cooling will be particularly discussed.
