Roll Force Measurement and Control System (Product Overview)

rolling mills. The RFS-4 System provides the mill operator continuous monitoring and display of roll separating force and differential forces balance. The system eliminates temperature-induced drift during the period that the mill is empty and provides local and remote indications that metal is in the mill or that the mill is overloaded.

TWS Slab Load Cells are strain gage sensors used to measure the roll force in rolling mills under harsh environments. The TWS load cell strain gage technology uses DC excitation to provide fast responses to the changes of force in the rolling mill. The shape and the high quality construction of the Mill Master Load Cells make them

Roll Separating Force - an overview ScienceDirect Topics

The roll separating forces obtained in a single-stage pass of 55% reduction and two two-stage passes of 14/39% and 20/33.6% reduction are given in Figure 15.4, measured when rolling the softer AISI 1008, deep-drawing quality steel. Figures 15.2 and 15.4 are quite similar. The dynamic response of the mill is also similar to the previously observed behaviour.
