At The Georgian Technical University, with the initiative and support of the rector, academician David Gurgenidze has begun to restore the rarities preserved in the university space.
Restoration works of the old lanterns installed near the first building are being carried out at the Faculty of Chemical Technologies and Metallurgy of GTU, in the laboratory of foundry production and new technological processes.
Zaza Akhvlediani, the representative of the Laboratory of Foundry Production and New Technological Processes, said that the lanterns commissioned in the 50s of the last Century have been restored and have completely preserved their original appearance.
“70 years ago, lanterns of the original construction were erected in front of the first building. By themselves, during this time, they were damaged. More than 60 denominations of cast iron details were processed during the restoration process. According to the project drawn up on the initiative of the rector, we had to preserve the original look of the lanterns as much as possible for this unique, which has no analogs, but we managed to do it. The process of molding the damaged details of the lanterns is almost finished. The second stage of the restoration works will start soon”, says Zaza Akhvlediani.
According to the rector of GTU, the first building of the university was commissioned in 1954. In the same year, lanterns were installed on its outer perimeter. The architects of the first building were Neprintsev and Glazkov, under whose guidance the lanterns were cast. As the academician David Gurgenidze mentioned, apart from creative activities, Mikheil Neprintsev was also involved in teaching. He taught at the Georgian State Polytechnic Institute in 1919-1929 and 1959-1962.
“The Georgian Technical University is one of the oldest higher educational institutions in the Georgian educational space, and therefore, the protection of each page of its history or construction, created by Georgian ancestors, has a great meaning for future generations. For this purpose, we have begun the restoration process of rarities, especially since the lanterns, which have no analogs and are also exclusive, are being restored. For me, as a teacher and rector, it is very important that students participate in the restoration. Also important is the fact that the laboratory of foundry production and new technological processes is the only one where it is possible to carry out the process of restoration works of artistic cast iron samples”, said David Gurgenidze.
For information: in the laboratory of foundry production and new technological processes at the Faculty of Chemical Technology and Metallurgy of GTU, which, depending on the specifics, is equipped and maintained with appropriate equipment for metal melting and production. The following works are performed: determination of the properties of molding sands; determination of the sizes of sand grains; Determination of air permeability of the molding mixture; Determination of humidity of the molding mixture; determination of the strength of the molding mixture; Types of models and their manufacture; The influence of the thermal conductivity of the mold on the cooling rate of the mold; Melting gray cast iron in an induction furnace; determination of melting point; Measurement of cast iron microstructure; Smelting of high-strength cast iron; heat treatment of high-strength cast iron; the effect of various parameters on the fluidity of the alloy; the shape and length of the liquid mesentery; the casting speed effect on the liquid middle length.
