Steel Dynamics Inc. (SDI) is modernizing automation systems at its Butler, Indiana, hot strip mill through a controls upgrade that supports rolling operations and associated thermal processing functions within the facility. By updating the automation architecture that supports rolling and temperature-controlled manufacturing operations throughout the mill, the project is expected to help maintain stable production and support future operational requirements.
SDI has commissioned SMS group, a provider of technology and plant solutions for the metals industry. SMS groups will replace legacy process automation systems with a new generation platform across the mill’s hot strip production line, which includes equipment and processes that rely on coordinated temperature control throughout steel manufacturing.
The upgrade will replace the existing X-Pact® ProBAS automation system with the latest X-Pact® Embedded platform. The project scope includes migration of process automation functions, hardware replacement, and software updates designed to minimize disruption to production while extending the life of the facility’s automation infrastructure.
The Butler facility produces hot-rolled steel products for a range of end markets. The project is designed to improve operational reliability, maintainability, and long-term performance for steel production serving automotive, construction, and industrial markets.
