Computer aided design, analysis and manufacturing of hot rolled bulb flat steel profiles [Sıcak haddelenmiş çelik hollanda profillerinin bilgisayar destekli tasarımı, analizi ve imalatı]

Abstract

In this study, roll-pass designs were designed and controlled rolling simulations were realized by using of Simufact Forming simulation tool based on finite element method for acquiring an asymmetrical profile with low carbon-micro alloyed steel used in ship buildings. Simulation aided manufacturing studies have been realized for eliminating the manufacturing defects and obtaining stress-strain curves, forces acting on the rollers and torque requirements at the inlets and the outlets of the rolling stands. Optimization studies of the production parameters to improve the final product mechanical properties. Mechanical tests and metallurgical tests have been applied to the production samples obtained by ensuring that the production parameters obtained in simulated support activities are used in prototype productions and the improvement of the mechanical properties of the profile with asymmetric section is provided. © 2020, TUBITAK.
