Development and Application of System for Rolling Parameters Calculation on Strip Cluster Mills

Based on different conventional and modern models,a system has been developed on calculation of hot and cold rolling force and energy parameters which suitable for 4-high,6-high,8-high and 20-high strip rolling mills.The rolling schedule pre-set,equal power adjustment,metal deformational resistance database and other models for hot rolling and cold rolling has been adopted in this system.The prediction precision is enhanced greatly.Through a number of tests and applications,it is proved that the maximum deviation of rolling force and power prediction is about 10%,whose result producted certain reference instruction function to practice.The development,applications and effects of the system are introduced in the paper.
