Manufacturing of tubes by forming
Szczygiel, Pavel ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This thesis deals with the basic methods of manufacture of tubes, especially focuses on the technology of seamless tubes. Assess the appropriateness and inappropriateness of individual production methods used and presents technology and types of lines used in practice. It describes in detail process of production seam pipes with a diameter of 116 mm and a length of 97 m in the plant ArcelorMittal Tubular Products Karviná a.s. Also describes in detail each operation in the working section of the strip preparation, welding and is reduced.

Manufacturing of tubes by rolling
Šimůnek, Petr ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
Thesis is focused on the analysis of various rolling methods used for production of seamless tubes. It is a literary study, which describes both methods for the production hollow thick-walled cylindrical billets, as well as methods for their processing into finished tubes. Comparison between them and practical use is also described. In the thesis are analysed the methods of production of hollow semifinished products by push rolling and cross rolling, e.g. Mannesmann and Stiefel methods. For the seamless tubes finishing various rolling methods are described, such as pilger mill, mandrel mill, plug mill, Assel mill, Diescher mill or pushing mill.

Diagonal rolling technology
Popp, Dominik ; Benč, Marek (referee) ; Podaný, Kamil (advisor)
The aim of the thesis is research in the field of diagonal rolling technology. First, the heating of the material, which is an integral part of most forming processes, is described. In particular, the prevention of undesirable phenomena that can occur during heating is mentioned. Also mentioned are the heating furnaces, most commonly found in rolling mills. Then the methods used in the initial stage of seamless tube production are presented. In addition to a description of the individual principles, the deformation behaviour of the material is outlined. Subsequently, a description of the finishing operations required to roll the tubes to final dimensions is discussed. In the last section are introduce special forming benches, which can be used to form threads, ball blanks or even ball pins, used in the suspension of passenger car wheels.

Surface temperature measurements by IR camera
FUKA, Miloš
The master's thesis is devoted to the history and performance of non-contact temperature measurement, characterization of infrared cameras and infrared thermometers. Temperature is one of the most important physical quantities. Using an infrared camera we obtain information about the surface temperature in all picture. In the master's thesis is included the measurement and capturing the fatal defects on the punched billet, finding out the quality of temperature field and the quality of the overlapping work rolls. During the measurements were used infrared cameras TIM200, TIM400 from the company Micro-Epsilon and infrared cameras SC325, SC660 from the company Flir.
