Influence of using the secondary metallurgy on steel properties

By Horymír Navrátil


This bachelor thesis describes metallurgical processes of production of steel in electric arc furnaces. It also describes oxidation and reduction phases of melting. Furthermore, it describes the main elements of secondary metallurgy used in steel foundries and their applications. The thesis also concerns with impurities in the steel, namely non-metallic inclusions, gases and trace elements, which is also connected with final utility properties of the steel. This thesis also describes in detail the technological properties of steel. The influence of several selected elements on steel properties is also described. Finally, the thesis evaluates the effect of secondary metallurgy on the volume of defects in steel castings, on mechanical properties and the resulting chemical composition
