EAF System Engineering
Engineering solutions to upgrade existing EAF systems, improve operational efficiency and increase steel production capacity.
Electric Arc Furnaces operate under extreme thermal and mechanical conditions. Over time, equipment wear and outdated design can limit furnace performance and energy efficiency. ATS provides engineering and modernization solutions to upgrade existing EAF systems, helping steel plants improve operational stability, productivity and equipment lifetime.
EAF Modernisation Scope
Electrode Arm & Electrode System Upgrades
Improving current carrying capacity and mechanical reliability. We design and upgrade electrode arms and electrode systems to support higher currents and more stable operation, reducing losses and extending component life.
Furnace Shell & Cooling System Improvements
Enhancing shell protection and extending furnace lifetime. Upgrades to the furnace shell and cooling systems improve thermal management and reduce the risk of hot spots and premature wear.
Slag Door & Tapping System Improvements
Optimizing slag handling and tapping operations. Improved slag door design and tapping systems enable safer, faster and more controlled tapping and slag handling.
Process Monitoring & Instrumentation
Thermal monitoring and process data collection for better operational control. We integrate sensors, thermal monitoring and data systems to support real-time process control and optimisation.
Furnace Platform & Mechanical Systems
Upgrading critical mechanical components and operational safety systems. Platform, tilting and mechanical systems are redesigned or upgraded for reliability, safety and ease of maintenance.
EAF Injection & Lance Systems
Optimizing Chemical Energy Input in Electric Arc Furnaces
Modern Electric Arc Furnaces rely not only on electrical energy but also on chemical energy to improve melting efficiency and productivity. Injection and lance systems play a key role in delivering oxygen, carbon and other gases into the furnace to support efficient melting, refining reactions and slag foaming.
Our engineering solutions support the design, optimization and technical evaluation of oxygen lances, injection nozzles and manipulator lance systems used in Electric Arc Furnace operations.
Oxygen injection into the molten bath enables oxidation reactions that accelerate melting and improve furnace productivity.
Why Modernise Your EAF
- Increase furnace productivity
- Reduce electrical energy consumption
- Improve operational reliability
- Extend furnace campaign life
- Improve safety conditions
Before & After
Our Engineering Approach
Furnace performance analysis
We review your current EAF layout, operating data and maintenance records to identify where performance and efficiency fall short of targets and where upgrades will deliver the best return.
Identification of operational bottlenecks
We pinpoint bottlenecks that limit productivity, energy efficiency or availability—in electrodes, shell and cooling, tapping, automation or safety—and agree priorities with your team for a focused scope.
Mechanical & process engineering redesign
For each scope item we deliver detailed engineering: electrode arms and systems, shell and cooling, slag door and tapping, instrumentation or platform and mechanical systems—ready for procurement and execution.
Implementation & commissioning support
We support installation, cold and hot commissioning, and tuning so the upgraded EAF reaches target performance, with coordination, procedures, training and handover documentation.
