| RH2 rail head hardening system |
ArcelorMittal Poland installed Danieli’s RH2 rail head hardening system to boost rail durability and energy efficiency.
RH2 Rail Head Hardening System Enhances Steel Quality and Production
ArcelorMittal Poland began operating the Danieli RH2 system at its Dąbrowa Górnicza plant. The system produces long rails up to 128 meters, achieving hardness above 400 HB. It improves wear resistance and ensures uniform mechanical properties along the rail length. The line’s productivity reaches 22.5 rails per hour. Furthermore, RH2 reduces operating costs by up to 45% due to its energy-efficient design, eliminating the need for air coolers and extra heating of rail ends.
Automation and Environmental Benefits of RH2 Technology
Developed at Danieli’s research center in Italy, the RH2 system uses advanced PLCs and HMIs for precise control. ArcelorMittal Poland now supplies premium rails meeting European and American standards with a lower carbon footprint. Recently, ArcelorMittal Poland also commissioned hydrogen furnaces in Krakow, enhancing product quality and reducing emissions. This PLN 52 million investment supports sustainable steel production and faster processing.
ScrapInsight Commentary
ArcelorMittal Poland’s adoption of the RH2 system signals a shift toward higher-quality, energy-efficient steel products. This upgrade aligns with growing industry demand for sustainable solutions and will likely improve competitive positioning in global rail markets.
