Popis: A procedure and algorithms are described for the calculation of the rolling power and the main-drive engine power and torque of a working stand in a cold-rolling mill with regard for the number of neutral sections in the deformation zone, including the case of two neutral sections in the deformation zone. This work is a continuation of our earlier work, where we were the first to consider a deformation zone with two neutral sections and proposed a procedure for the calculation of the contact stresses and rolling forces in it. Taking into account the second neutral section is shown to decrease the engine power calculation error by a factor of 4.5–6.5 (on average from 25 to 4%), which allows one not to use too high safety factors when choosing the power rating of the main drive in a cold-rolling mill.
