ArcelorMittal Poland Launches RH2 Rail Head Hardening System from Danieli

Danieli’s RH2 Rail Head Hardening System Boosts Rail Quality

ArcelorMittal Poland recently installed Danieli’s RH2 rail head hardening system at its Dąbrowa Górnicza plant. This advanced system produces long rails up to 128 meters with hardness exceeding 400 HB. The technology enhances wear resistance while maintaining uniform mechanical properties along the rail length. Moreover, RH2’s production rate reaches 22.5 rails per hour, supporting high-volume demand for premium railway materials.

The RH2 system uses innovative heat treatment and cooling methods developed at Danieli’s Butrio research center. Unlike conventional systems, RH2 eliminates the need for air coolers or extra heating on rail ends. As a result, ArcelorMittal Poland reduces operating energy costs by up to 45%. Automation via Danieli’s PLC and HMI solutions enables precise process control and consistent product quality.

Environmental and Industry Impact of RH2 Rail Head Hardening System

ArcelorMittal Poland now offers rails that meet stringent European and American standards. The company’s environmentally friendly hardening process supports sustainability by lowering the carbon footprint. This advancement complements ArcelorMittal’s recent PLN 52 million investment in hydrogen furnaces at its Krakow cold rolling annealing shop. The new furnace system improves rolled product quality and accelerates production while cutting emissions.

Overall, Danieli’s RH2 rail head hardening system strengthens ArcelorMittal Poland’s position in the global steel and railway markets. It offers customers superior rail durability with reduced environmental impact and operational costs.
