Abstract: This paper presents a finite-element simulation of the force and power characteristics of the cutting process in drum shears of the 1700 hot-rolling mill at JSC “Qarmet” using the DEFORM-3D software package. Geometric models of the tool and the workpiece were developed, and a computational setup was formed accounting for the kinematics of drum rotation and the variation of the inter-knife clearance along the “negative-zero-positive” trajectory. The workpiece material was specified as AISI 1015 steel with an initial temperature of 900° C; the contact interaction was defined using the Siebel friction law. The numerical results yielded time histories of the vertical cutting force, torque, and power for the upper and lower knives. The cutting process was shown to be distinctly unsteady; despite comparable vertical force levels, a pronounced asymmetry in torque and power distribution between the drums was observed, attributed to differences in knife geometry and to the location of the resultant contact force. It was established that the lower-drum knife of smaller diameter experiences the highest torque and power demand, and that peak values in the final cutting stage govern drive design. The obtained dependencies can be used to assess overload conditions, select motor rated power, and tune control systems of the drum-shear electric drive.
