Pyrum steel wire is extracted from the material flow using a powerful metal separation system. Before undergoing cleaning, the steel wire has a purity level of only around 80 per cent due to all the rubber and textile fibres extracted along with the wire and so is not yet pure enough for use in a steel mill.
This is why a second process step is needed in which the textile fibres and rubber adhesions are almost completely separated from the steel wires. At the end of this process, the Pyrum steel wire has a purity level of more than 96 per cent and so is suitable for use in steel mills. The rubber residues can be further processed to form granulates and then sent for thermolysis. Incidentally, for every tonne of steel and iron scrap used in steel production, the mining of 1.5 tonnes of iron ore is prevented.
