Abstract
The invention relates to a control device for a continuous multistand rolling mill, in particular a light section mill, which has a computer with a memory for rolling program-specific variables, e.g. rotational speed set point values, armature currents and exit cross-sections and for the calculation of derived variables, e.g. the rolling stock tensions between the stands, minimum tension control being performed by controlling the rotational speeds of the individual stands (1m;1n) of the mill via additional rotational-speed set point values, these values being formed in accordance with a predetermined computing rule taking into account stored empirical values (KE) and the additional rotational-speed set point values being formed in accordance with the following computing rule: <IMAGE>
