Based on a preliminary technological analysis of the operation of the Sinter Plant of the OJS company Novolipetsk Steel Plant and the use of statistical methods of paired and multiple regression, as well as monthly technical reports of the SP for 2015-2018, the influence of mix composition and technological parameters of the operation of sinter machines on the vertical speed of the sintering process, specific productivity of sinter machines, strength and yield of sinter, the content of FeO in it and specific consumption of solid fuel is studied The obtained dependencies can be used for predictive calculations.
