How it works

It replaces combustion in auxiliary processes and reheating compatible with low-emission electric heat.

Steel improvement combines lower emission routes, material performance, energy efficiency and water, air and waste control.

When does it make sense?

  • The production route and quality required are known
  • Energy, material and emissions balance can be measured
  • Product safety and durability are maintained

How to apply it

  1. 1

    Delimit the measurement and measure the starting position.

  2. 2

    Apply the measure with competent personnel and check for site-specific risks.

  3. 3

    Follow results, maintain the solution and correct unwanted effects.

Potential benefits

Lower resource intensity

Less emissions or waste

Increased use of steel

Limitations and precautions

  • The benefit must be verified under the actual conditions of application.
  • An improvement per tonne can coexist with more total emissions.
  • The routes depend on scrap, electricity, mineral and infrastructure available.
