Adaptive Fuzzy Vertical Vibration Suppression Control of
May 06, 2020· This paper investigates the adaptive fuzzy vertical vibration suppression control problem for the six-high rolling mill system. Firstly, a new vibration model is established with the consideration of the coupling of mechanical and hydraulic systems and the unknown uncertainty on nonlinear rolling force. Then, the adaptive active control strategy is proposed to suppress chatter of the rolling

Evolution of artificial defects during shape rolling
the process is limited by the maximum rolling force of the mill. At high temperatures, on the other hand, there is a risk of partial melting in grain boundaries because of the intense deformation heating during rolling. In such cases the bar collapses during rolling. Thus, in order to control the rolling
Sendzimir Z-High® Mills were developed to combine the advantages of the Sendzimir cluster-type rolling mill with those of the 4-High. The Z-High® concept permits the revamping of a classical 4-High mill with a system that uses amuch smaller work roll. This new configuration allows the mill to take heavier reductions per pass and achieve

Configurations Of Rolling Mills In Metal Rolling Operations
Three-high Rolling Mills: In a three-high rolling mill configuration, three rolls are placed face to face. With the reverse rotations of these rolls, the work part can be passed through these two rolling mechanisms consecutively. After each pass, the work part must be oriented to another pass. Some moving and elevator mechanisms can be required.
