Postgraduate students of the Department of Machines and Processes of Pressure Metal Working Al-Khuzaie Ahmed Saleem Oleiwi and Al-Jumaili Mohammed Jasim Mohammed successfully defended their dissertations on topics related to the pipe rolling industry. Their research was carried out under the guidance of Professor of the Department of Machines and Processes of Pressure Metal Working, Deputy Director General for Research of the Russian Research Institute of the Tube and Pipe Industry (RosNITI), Doctor of Sciences (Engineering) Aleksandr Vydrin. The research papers had been ready to be defended in spring, but the pandemic made its adjustments—meetings of the Dissertation Council in the field of "Metal Processing" were postponed until September.
The paper "Improving the Efficiency of the Process of Continuous Sleeve Rolling by Refining the Methods of Setting up the Pipe Rolling Mill" by Ahmed Saleem Oleiwi was presented first. The purpose of this research was to improve the accuracy of determining energy-power parameters in the continuous rolling of tubes. The work was carried out using a specialized software product QForm, which has been actively used by the department for several years both for scientific work and in the educational process. For physical modelling, Ahmed used the multifunctional complex Gleeble 3800, which has been available for many years at the SUSU Mechanical Engineering Research Institute. The results of this research have already found application in the improvement of pipe rolling modes at the enterprises of the TMK Company, which the scientific advisor of the postgraduates is an employee of.
Next, Mohammed Al-Jumaili defended his paper entitled "Improving the Accuracy of Determining Energy-power Parameters in the Continuous Rolling of Pipes Based on a Study of the Patterns of the Hardening and De-hardening Processes of Steel”. The purpose of his research was to increase the efficiency of the process of continuous sleeve rolling by improving the methods of setting the speed mode for the tube rolling unit. Most of his research was conducted at RosNITI, with which the department has close and long-term partnerships. Many the department's graduates are employees of this institute, and many RosNITI employees have been pleased to lecture and continue to give lectures to the department's students. This dissertation relates to the problems that the pipe-rolling industry faces.
It should be noted that the results of both works were presented multiple times at international conferences in Russia, Iraq, and Turkey.
