Longitudinal rolling
Sigmund, Lukáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis describes technology of hot-rolled profiles. It defines the conditions which must be fulfilled for successful process of rolling. Further is described process of producing a specific special profile, which is used as an intermediate for making car door hinge. The profile is made of structural steel S355J2. It is manufactured by VÚHŽ a.s., which uses reverse duo rolling stand with special work rolls. The thesis evaluates the usability, advantages, disadvantages and mechanical properties that are obtained after forming at high temperature.

Production of Rolled Profile and Its Verification by Using Numerical Simulation
Sigmund, Lukáš ; Lidmila, Zdeněk (referee) ; Řiháček, Jan (advisor)
The thesis deals with technology of hot-rolled profiles, describing total summary of principles and conditions this process is based on. There is a draft of a calibration of profile, the application of which is subsequently verified through a numerical simulation. Futher in the thesis also was verified the mechanical properties of applied construction steel S355J2 through the up-setting test and compared the results with the used material model in the simulation software Simufact Forming. Then, the test rolling of the calibrated profile was carried out. As a next step, the dimensions of the rolled bars were compared with the results of the simulation, on the basis of which the applicability and suitability of the simulation in the future development of other profiles was verified and evaluated.
