Online diameter measurement of ferrous wire on dry drawing benches

摘要

It is a well known fact that the major obstacle in expanding online diameter measuring practice in the wire industry is the high dust sensitivity of most optical instruments. This jeopardises applications on dry drawing benches, where soap and iron dust can strongly affect the measuring accuracy and blind the sensor in a short time. This report documents Aeroel's state-of-the-art laser measuring technology applied on dry drawing benches: ten years of field experience and continuous development have led to a reliable and effective solution of the aforementioned problem.
