Rolling Mill Roll

A 1450mm cold rolling mill roll stepped cooling control technology has been studied. The basic principle of stepped cooling control has been analyzed. The important role of stepped cooling control in the control of thermal crown has been elaborated. In order to analyze impact of stepped cooling on the sectional shape of the strip, the roll under the influence of the cooling water temperature field has been established. The model of optimal cooling capacity in each segment has been established. The model has been successfully applied to a 1450mm cold rolling mill roll, and a good effect has been achieved.

Control Capability

A 3D elastic-plastic finite element method (FEM) model of cold strip rolling for 6-high continuous variable crown (CVC) rolling mill was developed. The rolling force distributions were obtained by the internal iteration processes. The calculated error has been significantly reduced by the developed model. the absolute error between the simulated results and the actual values is obtained to be less than 10μm, and relative error is less than 1%. The developed model is significant in investigating the profile control capability of the CVC cold rolling mill in terms of work roll bending, intermediate roll bending and intermediate roll shifting.

Pilot cold rolling mill is the important tool for the cold rolling process researching and new steel grade development. According to the design of the new type direct pulling pilot cold rolling mill, based on the mass flow constant principle, strip exit thickness indirect measurement method is studied. During rolling, strip entry and exit speed can be calculated accurately according to the measured value of two sides’ clamps movement. Data filtering treatment is adopted and program flow chart is designed. Based on the material entry thickness measured manually, exit thickness of all passes can be measured indirectly. This thickness indirect measurement method has been applied successfully on the new type pilot cold rolling mill, and the measurement results show that this method has a good accuracy.
