With the RollKraft product line, IMS Messsysteme GmbH expands its portfolio to include force transducers for use in hot and cold rolling mills. The measurement systems provide precise measurement values for the control, analysis, and optimization of the rolling process and are designed for reliable use under demanding conditions at IMS Messsysteme GmbH.
Precise measurement values for stable rolling processes
A reliable measurement of the rolling force is crucial for strip thickness and strip flatness.
Ensuring material quality and process stability. RollKraft measures the force acting on the rolled product in the rolling stand and provides the measurement value for system control. The measurement is based on strain gauge technology. Under the applied rolling force, defined movements occur in the measurement zones specifically calculated and designed for the respective application using FEM analysis. The resulting signal change is converted into a force value via the IMS Force Controller (MMV). This value is then available for ongoing process control and process monitoring.
Recording complex load conditions
In rolling frames, not only vertical forces act on the force transducers. Depending on
