Vliv teplotně deformačních podmínek na strukturu a mechanické vlastnosti bezešvých trubek

Abstract

This thesis deals with the effects of thermal deformation conditions on the resulting structure and mechanical properties of seamless tubes to the Mannesmann pipe rolling mill plant, as TŽ. The investigated parameters of this work was primarily finishing rolling temperature, which has a significant effect on the mechanical properties and structure achieved. The present work is focused on evaluating the results of tensile test, impact energy and metallography of steel S355J2H. The experiment included samples of tubes after rolling on pilgrimage stool and after normalization of the walking beam furnace, which is included in the technological flow tube production.
