A Roll Wear Prediction Model in Hot Plate Rolling
In this paper, the wear of work roll in hot plate rolling is introduced and the parameters affecting wear mechanisms in hot strip mill are investigated. In addition, different wear mechanisms in hot rolling and the differences between these mechanisms in different stands are explained. Using the finite element method and the rolling equations, a work roll wear model is proposed. Wear is modeled...
متن کاملA neural network approach to the control of the plate width in hot plate mills
Deviation of a slab width from the desired value in hot plate mills has caused signijicant yield loss by trimming and demanded tighter width tolerances of rolled plates. This necessitates vertical rolling with considerable width accuracy. In this papec a slab width control system is proposed in order to meet the stringent requirement on the plate dimensional tolerance. The control system adopts...
متن کاملResearch on Crown & Flatness Allocation Strategy of Hot Rolling Mills
In order to present the reasonable crown of hot rolling mills, the bend force and shift position should be pre-computed in a reasonable manner, while maintaining a good profile. How to search the optimal crown trajectory in ratio crown range is the key problem. Crown and flatness allocation strategy is researched based on dynamic programming method which has been improved and optimized by the a...
متن کاملA Survey of the Looper-tension Control Technology in Hot Rolling Mills
Looper and tension control is important in hot strip mills because it affects the strip quality as well as strip threading. Moreover, the most difficult challange in the controller design and control performance comes from the interaction between looper angle and strip tension. Disturbances from several sources also cause a deterioration in control performance, and thus they should be rejected ...
متن کاملResearch and Application of Thickness Control Strategies in Steel Plate Rolling
Thickness accuracy of plate production depends on Automatic Gauge Control (AGC) in the plate mill area. A typical modern thickness control system design and implementation of a steel plate mill is discussed together with the impact on the design of process models, available measurements, available control actuators and material properties. A highlevel software design approach provides the abili...
