摘要：Reasons of increase of dynamic coefficients of main drive lines are discussed. Methods of their calculation and technical solutions for their reduction are offered by means of increase of elastic torsion angle of main drive lines during unsteady rolling when metal bites happen. According to results of calculations of elastic shaft-energy accumulator it was recommended to install it in motor section of #4A rolling stand of hot rolling mill 1700 of PJSC ‘ILYICH iron and steel works’ (Mariupol city, Ukraine).
