Summary
The rolling schedule of a multi-pass hot strip mill is simulated using the plane strain compression test with a computer controlled servohydraulic press. Actual rolling schedule data are converted by a user-written computer program into control signals for the testing machine. This includes the plastomechanical requirements for a desired average strain rate combined with a particular distribution of the strain rate curve. It also takes into account that at high strain rates or short interpass times the resulting ram displacement may differ greatly from the control signal. For this reason the machine characteristics have been calibrated. An electronic device combines the computer controlled ram movement with the motion of auxiliary tools. This ensures a reproducible and safe working sequence.
