Flatness is one of the most important qualities of plates. Most plates just after the rolling or cooling process, however, do not satisfy the flatness demand for customers. As the most particular flatness defects, edge wave and center buckle are well-known. In order to satisfy flatness limits, roller leveler is widely applied. In the roller leveling, the plastic deformation ratio that...

The current market is seeing an increase in the demand of added value products including the production of high strength plates which ideally must keep the use of high cost alloys to a minimum. Applications such as oil and gas pipelines, offshore structures and shipbuilding, require good control of both mechanical properties and the final shape of the plates. The production of such plate is...

Besides modern equipment and sophisticated process automation systems effective steel production requires a production management system which is coordinating the production processes on the shop floor and integrating those with the commercial processes. Implementation time has direct influence on the return of investment of such a system. The product driven project methodology, a new...

Flatness is an essential property for the quality of heavy plates. To achieve the flatness required by the customer, levelling machines are used for many types of plates. Today, flatness is described by means of the deviation of the plate topography from a 1 or 2 m ruler according to DIN EN 10029. This measurement method does not provide any further information about the type of flatness...
