ADJUSTABLE DESCALER

摘要

An adjustable descaling device for a rolling mill (20) for rolling a metal product (10) on a rolling line comprises one or more descalers (13a, 13b, 14a, 14b), at least one scale detection sensor (17, 18); and a processor (19). The sensor detects a scale pattern on a surface of the metal product (10) after descaling of the product. The processor adjusts the descaling impact pattern according to the detected scale pattern provided by the sensor.

1. An adjustable descaling device for a hot rolling mill for hot rolling a metal product on a rolling line, the descaling device comprising
one or more descalers, the descalers comprising high pressure water jets having nozzles configured for spraying water on the metal product on the rolling line; at least one scale detection sensor configured and operable to detect a scale pattern across a width of the metal product on a surface of the metal product after the descaling of the product; a processor configured and operable to adjust a descaling impact pattern of water sprayed on the metal product, according to the detected scale pattern provided by the sensor and according to a determined correlation between the detected scale pattern and a known pitch E of the descaling nozzles, wherein the processor is programmed to determine whether a standoff distance of the descaling nozzles from the metal product may not be optimum or wherein a very weak or zero correlation between the detected scale pattern and the pitch E of the descaling nozzles suggests that the scale pattern and the standoff distance of the water jets from the metal product are close to optimum.
