Research and Application of Pre-Bent Automatic Control Models of 100 Meters Rail

Abstract:

Repeated bending occurs toward the direction of rail head and rail base during the cooling which can lead to significant bending deformation and residual stress after cooling, the longer the rail, the more obvious this phenomenon is. In addition to cooling function, a kind of cooling bed with a pre-bent process will be used in order to solve this problem on 100 meters rail. The synchronous movements on this cooling bed can be realized by the automatic control system after establishing the mathematical model of bending deformation after rolling. The rail is reversely bent toward the rail base before cooling according to the pre-bent control of the pre-bent curve and is straight after cooling which can realize the control of the residual stress after pre-bent and straightening. The straightening residual stress significantly reduced after the pre-bent. Fund: National Natural Science Foundation funded projects （50765004）
