Abstract
Based on the heat transfer and solidification model for simulating two-phase zones by coupling multiple alloys during slab continuous casting process and the soft-reduction theory, the dynamic control model for soft-reduction on slab continuous casting was developed. The control model consists of three major functional modules: real-time tracking simulation, cooling water control and dynamic soft-reduction control. In order to keep stable continuous casting and produce high quality slabs during slab continuous casting process, many significant operating parameters such as the cooling water at the secondary cooling zone and the roll gap at sector section can be dynamically adjusted according to the reasonable metallurgical criterion and on-line feedback information. Industrially, the model has been successfully applied. Industrial practices indicate that the control model with reasonable algorithms and accurate simulation has a certain theoretical value and industrial practicality.
