Primetals Technologies has partnered with Çolakoğlu Metalurji to upgrade its Electric Arc Furnace (EAF).
Çolakoğlu Metalurji, located in Dilovasi, Türkiye, is setting new standards in steel production efficiency with the upgrade.
The revamped EAF installation introduces a furnace-tilting-device that enhances movement precision and velocity. Together with the implementation of an electromagnetic stirrer (EMS) system, supplied by ABB, the upgrade positions Çolakoğlu at the forefront of electric steelmaking.
This not only increases operational reliability and energy efficiency but also improves furnace accessibility and maintainability.
The modernisation marks a significant step toward Çolakoğlu's commitment to sustainable and high-productivity steelmaking, combining robust mechanical design with cutting-edge automation and data intelligence.
The project at Çolakoğlu Metalurji presented significant engineering challenges, requiring the integration of new mechanical and hydraulic assemblies into the existing EAF within a brownfield environment.
Unlike a greenfield project, this upgrade demanded precise alignment of the tilting mechanism, frame structures, and EMS system with the current foundation, furnace shell, and plant infrastructure.
All work was completed within a tightly scheduled four-week timeframe, including dismantling, structural adaptation, reinstallation, and commissioning.
Working in the confined furnace bay added complexity, requiring exact interface management, precise prefabrication, and smart logistics. Completing all mechanical and hydraulic work on time — while ensuring safety, quality, and long-term reliability — was a central challenge of the project.
To meet the demanding timeline and integration requirements, Primetals Technologies and Çolakoğlu Metalurji adopted a comprehensive engineering and installation strategy.
All new assemblies were preassembled and precisely aligned during fabrication using detailed 3D models and custom Primetals Technologies drawings. This modular approach enabled rapid on-site installation and minimised interface adjustments during construction.
Through modular preassembly, optimised logistics, and precise scheduling, the project was completed on time.
