Resumo

It is not rare to observe an inverse relationship between hot strength determined from rolling load of the finishing stands of the hot strip mill and strain. This situation was already described in the literature and is explained by the use of inverse rolling load models that assumes sticking friction in the determination of hot strength. The aim of this work was to show that this “work softening” effect is fictitious, disappearing when hot strength is calculated with an inverse rolling load model that properly takes account of the tribological conditions that prevail in the roll gap.
