Zinc monitoring

Zinc-monitoring can be combined with dynamic wiping. After being calibrated the zinc monitoring unit measures the zinc on the wire continuously, trims the nitrogen flow accordingly and sends signals when necessary (e.g. to alert to the state of the nitrogen nozzle). Consequently, any substantial drift in zinc coating weight can be detected. This is a major support for the operator. FIB has already equipped twenty-five lines with this system so far (2011).
