Finishing mill is an unit in hot strip mill plant which regulatesthe thickness of the steel plates in order to get thedesired thickness. Finishing mill is a high complexity unit due to therequirement of a combination of automatic control systems and manualcontrol systems in the operation. Failure in this process will producedefect products that would result in losses for the company.Therefore, an operator must understand the process and operation forthis unit. Operator training simulator (OTS) is a tool that representsthe dynamics of the process and the control system of a plant whichcan be used as a training tool to improve the ability of the operatorin order to understand the dynamics of the process of finishingmill and to train the response of the operator in the abnormalcircumstances such as bending, shifting and tilting. Finisihing millprocess dynamics are modeled using several dynamics equations whichparameter values are estimated by minimizing the error functionbetween the data model output with the actual output. Furthermore, themodel is validated by using an average ratio of RMSE values withactual values of looper angle, tension steel plates, and the loopertorque. The average ratio are respectively 6.401%, 4.3338%, and 1.9078%. RMSE value describes distribution of model value around actual value. Small average ratio of the RMSE value and actual value indicate a good model because distribution of model value close to actual value.
