Improving the manufacturing technology of structural steels

Abstract

"The industrial research investigates the influence of chemical composition and rolling technological factors on the mechanical properties of structural alloyed steel. Determination of the influence of the rolling technological factors on the mechanical characteristics was a difficult problem due to the lack of the research equipment for measuring with sufficient precision, under exploitation conditions, of the rolled product temperature and due to the dependence of this factor on the entire complex of the other technological parameters. The completion of the study required the expansion of research into the construction of equipment for measuring the temperature of small-sized rolled products and the cooling rate, to meet the requirements of current practice. The research carried out under industrial conditions specifies the contribution brought on the qualitative characteristics of the studied structural steel, according to the technological factors of the process."
