Description

technical field

[0001] The present application relates to the field of metal material processing, in particular to a debugging method for a single-stand cold rolling force model and a forward slip model. Background technique

[0002] The rolling force model and the forward sliding model are the core models of the entire single-stand cold rolling process control. The calculation accuracy of the model determines the process control accuracy and the stability of the rolling process. In the single-stand cold rolling process control, the rolling force and The setting calculation of forward slip is the main content of the model system, and the calculation accuracy of rolling force and forward slip setting depends on the calculation accuracy of strip deformation resistance and friction coefficient.

[0003] The deformation resistance of strip steel is often obtained by tensile test method, and the friction coefficient is measured by rolling test method or special testing machine. ...
