A ROLLING MILL DATA ACQUISITION AND ANALYSIS SYSTEM FOR EFFICIENT MILL PERFORMANCE

摘要

In a rolling mill no load roll gap is set based on mathematical model. This mathematical model requires a set of parameter which is to be acquired at an interval of 20 m sec and provide these inputs to the model. The data is to be analyzed to find out the reason of off gauge and the reason of a cobble. The rolling mill system of the invention is adapted to acquire data using a programmable controller with fast response analog and digital input module and provides inputs to a model. The invention also provides for data analysis to find out the reason of a cobble and reason of off gauge. The system basically comprises of a programmable controller, analog and digital input modules, Isolation devices, programming terminal and HMI unit for operator"s guidance.
