Aiming at predicting what happens in reality inside mills, the contact parameters of iron ore particles for discrete element method (DEM) simulations should be determined accurately. To allow the irregular shape to be accurately determined, the sphere clump method was employed in modelling the particle shape. The inter-particle contact parameters were systematically altered whilst the contact p...

In the face of global energy crisis, use hybrid technology is an important way to achieve efficient storage and utilization. Hybrid systems have been successfully applied automobiles construction machinery, but no research study has conducted on design application recovery for reversible rolling mills. This article proposes a new type noncoaxial parallel electrohydraulic drive system configurat...

This paper proposes the eccentric problem in the coiling process of cold rolling mills. The wavelets multiresolution control method is designed: A wavelets multi-resolution controller is introduced in the control cycle of coiling tension control, whose purpose is to acquire the element caused by periodically change of the coiling eccentricity. Then the signal without effectiveness of the coilin...
