Rocky Mountain Steel Mills has begun hot commissioning activities at its new Danieli universal rail mill in Pueblo, Colorado. Rocky Mountain Steel Mills is part of Orion Steel, a U.S. producer of engineered steel products for rail and industrial sectors.
The new rail mill is designed to produce 650,000 short tons per year of high-quality, flat-bottom and thick-web rails. The rails will be up to 88 kg/m, in lengths of up to 100 meters, with hardness reaching 425 BHN. The rails produced meet AREMA specifications and are suitable for heavy-haul and high-speed railway applications.
Key technological areas under commissioning include the break down mill (BDM), tandem reversing mill (UFR), cooling bed, and the horizontal and vertical straighteners. Hot trials are underway, and startup activities are progressing according to plan.
