Vliv parametrů ochlazování na mechanické vlastnosti bezešvých ocelových čtyřhranných profilů

Abstract

This bachelor thesis deals with the production of seamless pipe and seamless square section in a tube mill of Třinecké železárny. In next part of theory is effect of cooling on the microstructure of steel, which affects the mechanical properties of the material. In the experimental part, the results of mechanical properties and microstructure of the material are dicussed. The result of the work is a summary and comparison of two square sections cooled under two different conditions.
