Month after month, several million linear metres of aluminium strip and foil as well as various other nonferrous metals leave the major metallurgical works. From hot and cold rolling and via various finishing stages the coils are precisely recorded for their quality parameters and documented through the process steps. The strip ends are often outside tolerance limits, with excess thickness or imperfect flatness, and end up as scrap. Because of that the retrieval of defined strip sections becomes increasingly difficult. But thickness protocols and surface inspection demand length-related assignment. That requires a new quality of material tracking.
