Abstract (en)

[origin: EP2548665A1] The method involves determining roll goods variable (S2) and determining a sliding zone for each of roll goods section based on a set of process variables. The process variables are arranged in connection with roller structure variables of a roller structure. A respective relative movement dependent wear component is determined by taking length of respective sliding zone into account. A relationship is determined for the respective relative movement dependent wear component. Independent claims are also included for the following: (1) a computer program having a set of instructions for performing a method for investigating wear of a roller (2) a rolling mill.
