Deacero, Mexico's prominent steel producer, commissions Danieli for a cutting-edge 1.5 Mtpy minimill aimed at bolstering large sections production, doubling capacity at the Ramos Arizpe site. The facility, featuring advanced technologies, including a 150-ton EAF and automated systems, ensures high performance, optimized energy use, and competitive green steel output.


Deacero, a leading steel giant in Mexico, has entrusted Danieli with the construction of a state-of-the-art 1.5 Mtpy minimill, set to revolutionize large sections production, effectively doubling capacity at the Ramos Arizpe site. This significant investment marks the fifth collaboration between Deacero and Danieli in the realm of minimills.

Strategically positioned within the existing facilities at Ramos Arizpe, this new minimill will seamlessly complement the current setup, which specializes in small sections, producing approximately 1.5 Mtpy of sections ranging from ¼ to 10”. Notably, this existing plant was also a Danieli creation.

Deacero's relentless pursuit of cutting-edge technology is evident throughout the new minimill's design. From scrap processing to melting and secondary refining, beam blank and billet conticasting, hot-rolling, and finishing, the facility promises peak performance while optimizing energy consumption for the production of Competitive Green Steel.

The steelmaking complex is set to feature a 150-ton “Zero-Man-Around” EAF, supported by an automatic raw material handling system that facilitates ECS endless scrap charging. Additionally, it will house a twin LF secondary refining station.

Further enhancing the production capabilities, a high-capacity six-strand continuous casting machine will deliver a range of billets, blooms, mini-slabs, and beam blanks, catering to various requirements.

The heart of the operation, the heavy-duty medium section mill, boasts cutting-edge technology. It will be powered by a 180-tph walking-beam reheating furnace and equipped with a breakdown mill (BDM), an ultra-flexible reversing mill (UFR), and advanced stands for comprehensive straightening and finishing services for sections up to 27” (702 mm).

Danieli Automation solutions, including the Q3 Platform and Q-Drive, will drive the minimill's operations, enabling seamless integration, data-driven decision-making, and high-performance drives for the section mill.

The plant's launch is scheduled for the first quarter of 2026, marking a transformative step in Deacero's pursuit of innovation and enhanced production capacity.


Deacero's collaboration with Danieli for this high-tech minimill stands as a testament to their commitment to innovation and sustainable steel production. The implementation of state-of-the-art technology, advanced automation, and optimized processes highlights their dedication to pushing the boundaries of steel manufacturing, heralding a new era of enhanced capacity and eco-friendly practices in the industry.
