The 34th International Conference on Metallurgy and Materials METAL 2025 was held in Brno on 21-23 May 2025 . A total of 64 lectures and 85 posters were prepared for 170 participants from 27 countries.

The conference was opened by Professor Stanislaw Turczyn from AGH University of Science and Technology in Cracow with a lecture on Rolling as the important manufacture’s method of high quality steel products.

The second plenary lecture was given by Associate Professor Karel Saksl from the Institute of Materials Research, SAS, in Košice. His lecture was devoted to the topic of High-entropy alloys and oxides for energy storage applications.

However, as usual, the thematic scope of the conference lectures was much broader. Researchers presented innovations not only in the fields of iron, steel, cast iron, non-ferrous metals and alloys, metal forming and surface engineering, but also in economics and metallurgical production management.

The accompanying exhibitions of the sponsoring companies were also very enriching. The main sponsors of this year's conference were Messer Technogas s.r.o. and Struers GmbH, whose representatives also presented two very interesting lectures. Other exhibitors this year included Anamet s.r.o., Elementar Analysensysteme GmbH, and KEYENCE International.

The award for the best poster went to Michaela ŠTAMBORSKÁ from the Institute of Materials and Machine Mechanics of the SAS in Bratislava.

The next 35th edition of the METAL conference will take place in May 2026.

Abstract: In the iron ore sintering process, ensuring permeability to allow an appropriate amount of air to pass through the mixed raw material layer in the sintering machine and flow smoothly from top to bottom is crucial for the progress of the combustion zone and sinter productivity. Moisture control is vital for the granulation and air permeability of the mixed raw materials. [..] Read more

Abstract: Next generation casting technologies such as thin slab, belt or strip casting have gained popularity due to the reported energy saving, which can be as high as 1.6GJ/tonne when compared to conventional thick slab casting. However, these casting approaches result in changes in cooling rate during solidification and in thickness reduction to the required product geometry, which could affect the resulting microstructure and elemental segregation.

Abstract: The recycling of metal waste and scrap is an essential component of a circular economy, which is predicated on the principles of reducing waste and consumption of resources through the reuse and recycling of materials. However, it is not always possible to process the metal while maintaining its chemical composition and producing high-quality ingots without complicating the technological process and incurring excessive costs.

Abstract: Real-time measurements in steel continuous casting are challenging due to extreme temperatures, leading to limited process understanding and frequent breakouts. This project aims to address this issue of casting process control by simulating steel flow using a low-melting-point Bi-Sn alloy with steel-like properties, enabling real-time analysis of pressure, velocity, vibrations, and mold level fluctuations to optimize stopper-nozzle designs.

Abstract: The presented research focuses on identifying differences in the lengths of transition areas during the continuous casting of steel in a three-strand "T"-type tundish, considering various numbers of active strands. The study compares results from three types of measurements: in the first measurement, casting was simulated with three active strands (full capacity); in the second measurement, the simulation was realised with the middle strand disabled; and in the third measurement, the continuous casting process was simulated with one of the outer strands disabled.
