Over the life span of a rolling mill, the requirements in terms of product quality and the range of steel grades may change significantly. In particular, the capability of the installed hydromechanical descaling systems needs to be investigated as one of the key technology areas when it comes to process modifications and surface quality improvements. The introduction of modern strip surface inspection systems has also intensified the focus on the optimization of descaling systems. A descaling system audit is a systematic and structured approach to determine how the existing nozzle and header arrangement, operational and maintenance practices, and process data influence the surface quality.
