The F3 mill stand in the model was applied simply as a roll bite that provides the clamping support of the strip during transmitting and upon escaping. A tension of 10 t in magnitude was applied to the front of the strip model to facilitate the continuous finishing. Thus, the backup rolls were neglected from the F3 model for simplicity.

In the Steckel mill, it is necessary to guide the strip backwards and forwards through the stand, like in the roughing stand. Since there is only one stand in a Steckel mill, it has a lower establishment cost but has on the other hand a lower production rate. Two problems arise, if a strip is brought backwards and forwards through a mill stand.
