The looper control of hot strip finishing mill is one of the most critical control items in hot strip rolling mill process. It is a highly complex nonlinear system, with strong states coupling and uncertainty that present a difficult control challenge. Loopers are placed between finishing mill stands not only to control the mass flow of the two stands but also …
Rolling mills are categorised based on the number and arrangement of rolls in a stand, and there are six common types: Two-High Rolling Mill It consists of two high stands and rolls placed one over the other, where the rollers rotate in opposite directions after each metal pass, requiring approximately 25-30 passes to convert an ingot to a bloom.
The vertical vibration often occurs during the rolling production, which has an influence on the accuracy of rolling mill. In order to effectively suppress the vertical vibration of the rolling equipment, the rolling mill model with vibration absorber device was established. Based on the main resonance singularity of the rolling mill system, the best …

Thrust bearings are ideal for applications experiencing heavy axial loads, such as mill stands, screwdown systems and piercing mills. • Ball bearings – Ball bearings are used extensively in
The main production unit is the rolling mill. This represents the grouping of different numbers of rolling stands into a production line. The number of rolling stands can vary from one to twelve and can be higher if necessary. Lines for coarse billets usually have a smaller number of rolling stands and larger removals, and the operations are ...

mill has to be calculated e.g. through a heat balance. The maximum admissible mill inlet temperature is < 450 [C]. Gas speeds: The mill has to be sized to meet the required speed ranges: e Nozzle ring: = 30 [m/s], higher speeds can be adjusted by covering nozzles e Mill casing: 4.5 - 7 [m/s] for vertical transport
Rolling is the most widely used deformation process. It consists of passing metal between two rollers, which exert compressive stresses, reducing the metal thickness. Where simple shapes are to be made in large quantity, rolling is the most economical process. Rolled products include sheets, structural shapes and rails as well as …
