 The object of research is the technology of production of particularly thin staffs on large-scale hot rolling mills and the resource of equipment. The purpose of the work is to create a theoretical basis and develop a computer system for optimizing the modes of hot rolling of thin headquarters and forecasting the residual life of equipment with testing in the current rolling mills. Research methods - mathematical modeling, experimental industrial research of temperature-speed and power parameters of rolling of thin large-scale rolling. The following tasks are solved in the work: methods of calculation of parameters of hot rolling of especially thin staffs taking into account microstructure and mechanical properties of steels are developed; the algorithm of adaptation of models of hot rolling of thin and ultrathin staffs according to data of measurement of current loadings of the main electric drives of various type is developed; developed and tested a mathematical model of the profile of the cross section and flatness of the headquarters; the basic approaches to the analysis of a residual resource of elements of the equipment of stands are developed; substantiated and accepted working model for residual life calculation for each type of parts used in large-scale hot rolling mills (spindles, gears, bearings, couplings, rolls). An innovative computer system for optimizing the hot rolling modes of thin headquarters and forecasting the residual life of large-scale equipment has been developed. The system was successfully tested in the conditions of the hot strip mill 1680 of PJSC "Zaporizhzhya Metallurgical Plant"Zaporizhstal".
