Stricter environmental legislations and rising energy costs force metallurgical plant builders and steel producers to constantly increase their energy and resource efficiency. Consequently hydro mechanical descaling systems need to be designed in such way that the conventional high safety margins resulting in excessive spray overlaps must be eliminated. Latest technologies have been applied to the new measurements of all variables which form the basis for the new edition of the DESCALE 7.5 software which is an indispensable tool for the design of descaling headers. In order to verify these digital values under a more practical approach, two additional and complementary methods have been utilised which will also be discussed in the paper. Both methods, the aluminium erosion method and the new hot descaling test, the latter representing real conditions, have a very high degree of agreement of the values and the results. Details of all three methods and the results will be discussed.
