Adjustable descaler and operating method of an adjustable descaler

摘要

An adjustable descaling device for a hot rolling mill (20) for hot rolling of a metal product in a rolling line, where the descaling device comprises one or more descalers, where the descalers comprise high water jets Pressure; at least one inlay sensor (17, 18); and a processor (19); wherein the sensor (17, 18) is adapted to detect an embedding pattern along the width of the product on a metal product surface (10) after product descaling, characterized in that the processor (19) is adapted for adjusting a pattern of descaling impact, in accordance with the detected embedding pattern provided by the sensor and a determined correlation between the detected embedding pattern and a known step E of the descaling nozzles, suggesting that the separation distance of the descaling nozzles may not be optimal or in which the weak or zero correlation between the detected embedding pattern and the step E of the descaling nozzles is used to suggest that the embedding pattern and the separation distance of the nozzle are almost optimal.
