ABOUT KOSH IN DETAIL
Science, engineering and industrial implementation in one cycle
NVF KOSH LLC was founded in 1994. The company develops and implements innovative technologies for the mining and metallurgical industry to reduce energy consumption per tonne of steel and introduce new environmentally clean energy sources. This work contributes to Ukraine’s energy security.
Implemented projects. The company developed and implemented hybrid pelletized feedstock at the Central Mining and Processing Plant, improving the properties of raw materials used in blast furnace production.
NVF KOSH developed a protective coating technology for blast furnace tuyeres and implemented it at Zaporizhstal and ArcelorMittal Kryvyi Rih. The solution was incorporated into the tuyere manufacturing process specification.
The company completed a series of projects implementing interactive burden-charging systems in the Zaporizhstal blast furnace shop. The latest work on Blast Furnace No. 3 in 2023 and 2025–2026 reduced coke consumption by 14 kg per tonne of hot metal.
NVF KOSH also implemented a project at Zaporizhstal to preheat natural gas before it enters the tuyere assemblies. The project reduced coke consumption by 5 kg per tonne of hot metal.
Research and patents. The company conducted industrial trials of nanofluids to increase the yield of usable sinter in the Zaporizhstal sinter plant. In 2023, NVF KOSH developed technical solutions to improve the efficiency of blast furnace hot-blast stoves and heat exchangers and obtained patents for the related inventions.
Team and cooperation. The company employs four Doctors of Technical Sciences, five Candidates of Technical Sciences and highly qualified engineering staff. NVF KOSH has cooperation agreements with institutes of the National Academy of Sciences of Ukraine and the Ukrainian State University of Science and Technologies.

CURRENT FLAGSHIP PROJECT
Clean steel production using small modular reactors
NVF KOSH LLC is developing a technology for producing clean steels using small modular high-temperature reactors. The solution offers advantages over conventional direct steelmaking technologies and supports a broad range of steel grades, including nickel- and chromium-alloyed steels. The process uses hydrogen circulation and achieves zero CO₂ emissions.
The project supports the energy security of Ukraine’s mining and metallurgical industry and the development of green steel production capacity worldwide.
