Computer Aided Design, Analysis and Manufacturing of Hot Rolled Bulb Flat Steel Profiles

Abstract

In this study, roll-pass designs were designed and controlled rolling simulations were realized byusing of Simufact Forming simulation tool based on finite element method for acquiring an asymmetrical profilewith low carbon- micro alloyed steel used in ship buildings. Simulation aided manufacturing studies have beenrealized for eliminating the manufacturing defects and obtaining stress-strain curves, forces acting on the rollersand torque requirements at the inlets and the outlets of the rolling stands. Optimization studies of the productionparameters to improve the final product mechanical properties. Mechanical tests and metallurgical tests havebeen applied to the production samples obtained by ensuring that the production parameters obtained insimulated support activities are used in prototype productions and the improvement of the mechanical propertiesof the profile with asymmetric section is provided.
