Possibility to implement oxy-hydrogen burners

By implementing oxy-hydrogen burners at your ladle preheating stations, you will vastly increase the possibility to decrease the CO₂ emissions at your site.

Ready-to-use oxy-fuel technology for reheating furnaces

Reheating furnaces can be upgraded with the most recent oxy-fuel technology, providing the possibility of reducing fuel consumption by your furnace and the associated CO₂ .

Technology available to implement O₂ supersonic oscillating jets at your EAF

Implementing SCOPE-JET Swing technology at your site will provide your EAF the possibility to use self-induced oscillation for your O₂ jet. This pertains to an increase in the bath surface affected by the supersonic O₂ jet.

Oxy-fuel technologies: the first steps to enrich carbon neutrality
The use of oxy-hydrogen combustion technologies at your ladle preheating stations, or the use of oxy-combustion technologies at your reheating furnaces, allows for the reduction of your greenhouse gases (GHG) emissions. If this is your goal, then applying oxy-combustion technologies is the first indirect electrification step to be made at your site.

Client: Oxygen use in steel reheating furnace

We introduced oxygen into steel reheating furnace process in order to reduce energy consumption.

  • Introducing oxygen into steel reheating furnace process in order to reduce energy consumption.
  • Overview of the Mini Mill process:
    • 1. Electric arc furnace produces molten steel
    2. Molten steel enters a steel refining facility
    3. Undergoes continuous casting
    4. After which enters the reheat furnace
    5. Produces final products: structural profiles, bars, slabs, etc.
  1. Initial inspection of the furnace in order to fully understand the problem
  2. Taking into account (amongst others):
    3. - Furnace type
    - Nominal production rate
    - Actual throughput
    - Charge dimensions
    - Specific energy consumption
    - Internal pressure
  3. Split into multiple cases to properly simulate the problem and model the solutions
  4. Installed an oxygen control skid with automatic flow control (0-900nm3/h) and electric cabinet with PLC and HMI screen
  • The solution was a success, with good operation and no instances of quality problems, temperature problems or refractory damage
  • This resulted in energy savings (8.3% average), reduced CO2 emissions (4.6 kg/Ton average) and reduced production costs
