Roll separating force in hot rolling under grooved rolls – A finite element analysis and experimental validation

Abstract

Finite element modeling and simulation of hot rolling under grooved roll has been carried out using commercial finite element based software ABAQUS^® to compute roll separating force at rolling stand # 3 of Wire Rod Mill, TATA Steel Ltd. Online measurement of rolling load has been carried out using load cell for validation of simulation results. Other than experimental validation, simulated results are compared with published empirical relations. It has been found that at elevated temperature, rolling load decreases with increasing carbon content in plain carbon-manganese steel.
