Using scrap as raw material is becoming more and more popular all over the world, and the need will only increase. As for the Nordic countries, it will be especially visible when SSAB’s production goes from ore-based to scrap-based in their arc furnaces, and with the establishment of H2GS. Also in China for example they are transforming the steel production to a much higher degree “secondary” (based on scrap) of the total output.
In other words, we have to use more produced iron raw materials, such as pig iron and HBI. But equally important – we need to make sure all resources in the form of residues are being used.
One briquette – a whole bunch of residues
Carbomax has produced thousands of tons of Fe-briquettes for recycling in arc furnaces over the last decade, based on several residues. But our next step is to mix a larger spread of residues with iron content, creating an iron briquette with uniform analysis over time – which makes it simple and predictable to use. This briquette can be based on several different residues with a known analysis, making it possible to continuously work with adjustments of the recipe.
