The application features of mathematical apparatus of harmonic analysis to determine the accuracy of rolled pipes

The degree of influence of the tube rolling unit mills on formation of wall thickness variation is investigated. Using the mathematical apparatus of the Fourier transforms, the amplitudes of harmonic components that describe various types of wall thickness variation are distinguished. The proposed computerized approach for rolling process control is focused on mathematical simulations processing of control of wall thickness variation of sleeves, of rough and fi nished pipes to increase their accuracy.
