Transforming Steel Production with Smarter Carbon Injection
In modern steelmaking, precision and sustainability go hand in hand. At Steltech, we focus on engineering solutions that boost efficiency, cut costs, and deliver higher-quality steel. One of the most powerful innovations in this space is the Carbon Multi-Point Injection System for Electric Arc Furnaces (EAFs).
By ensuring accurate carbon dosing and even distribution, this system helps steel plants maximize output, reduce waste, and stay competitive in an increasingly eco-conscious industry.
Why Electric Arc Furnaces Depend on Carbon
EAFs are at the heart of sustainable steelmaking. Unlike traditional blast furnaces, they melt recycled steel scrap using electricity, lowering both raw material needs and emissions. But to achieve the right steel chemistry, carbon is essential.
Carbon improves:
-
Deoxidation – removing oxygen
-
Carburization – strengthening the steel
-
Energy efficiency – improving melting speed
Old single-point methods often cause uneven distribution or excess use. Multi-point injection solves this challenge with precision.
How Multi-Point Carbon Injection Works
The process integrates storage, dosing, injection, and automation:
-
Storage – A large silo holds carbon powder with dust-free pneumatic filling and clog-prevention systems.
-
Dosing – A pressurized chamber measures carbon with 0.05% accuracy, ensuring exact delivery.
-
Injection – Multiple independent lines inject carbon directly into the molten bath for even mixing.
-
Automation – PLC controls and HMI panels allow real-time adjustments and data logging.
This system acts like a finely tuned delivery network, ensuring steel chemistry remains consistent and efficient.
Benefits for Steel Plants
Adopting multi-point injection brings significant operational gains:
-
10–20% savings on carbon consumption
-
Higher steel yield per batch
-
Shorter melting cycles
-
Reduced CO₂ emissions
-
Reliable, durable design tested for harsh industrial environments
At Steltech, we’ve seen these systems pay for themselves quickly. For example, a project valued at ~€185,000 demonstrated a fast return on investment thanks to improved productivity.
