Fireproof (or refractory) materials protect ovens and pots against the extremely high temperatures of metallurgical processes. But what if they have to be replaced themselves? Orbix demetallises the fireproof bricks and sorts them into different types of material so they will enjoy maximum reutilisation. Right now we are working on a state-of-the-art vision system that makes it possible to separate the materials entirely automatically. In this way they easily find a new use. The mineral fractions from the fireproof bricks can be used to develop new bricks, as soil improver/fertiliser, or as an alternative for dolomite.
