ǂThe ǂnew role of sustainable hydropower in flexible energy systems and its technical evolution through innovation and digitalization
Elena Vagnoni, Dogan Gezer, Ioannis Anagnostopoulos, Giovanna Cavazzini, Eduard Doujak, Marko Hočevar, Pavel Rudolf
Izvirni znanstveni članek
Oznake: hydropower energy;sustainability;flexibility;digitalization;
Hydropower has played an important role in Europe in recent decades, offering a unique combination of safe, low-cost, and clean power generation. Today, it is still one of the largest renewable energy sources (RES), accounting for about 35 % of RES electricity generation. However, grid stability is ...

Modelling of the solidification process and the chemical heterogeneity of a 26NiCrMoV115 steel ingot
Martin Balcar, Rudolf Železný, Ludvík Martínek, Pavel Fila, Jiří Bažan
Izvirni znanstveni članek
Oznake: forging ingot;solidification heterogeneity;modelling of segregations;
Steel making at ŽĎAS, a.s. using secondary metallurgy technology makes it possible to produce liquid metal with high levels of metallurgical cleanliness. During the casting and subsequent cooling of forging ingots, the steel solidification takes place. Directional material solidification, grain size ...

Detection of Divaška Jama corridors behind (to the SW) Trhlovca cave using low frequency high power ground penetrating radar
Pavel Kalenda, Rudolf Tengler, Stanka Šebela, Matej Blatnik, Andrej Gosar
Izvirni znanstveni članek
Oznake: ground penetrating radar;caves;karst;Divaška Jama;Trhlovca;Slovenia
Ground penetrating radar (GPR) named “Roteg” was used to detect known and unknown passages of Divaška Jama and Trhlovca caves in SW Slovenia. “Roteg’s” main characteristics are an extraordinary high power output (20 MW) and high voltage on antennas (up to 20 kV), which allows penetration more than t ...

Developing and testing a new type-8K mould for tool-steel ingot casting
Martin Balcar, Libor Sochor, Rudolf Železný, Pavel Fila, Ludvík Martínek, Libor Kraus, Dušan Kešner, Jiří Bažan
Strokovni članek
Oznake: tool steel;mould;ingot casting;solidification;forging;ultrasonic testing;
The traditional production of machinery and tools at ŽĎAS, a. s., and the increasing requirements placed on the final product, particularly those related to the internal quality of forgings, requires new technological measures for the ingot's casting and solidification. The development and use of th ...
