Reguliranje sadržaja dušika pri proizvodnji čelika u kisikovim konvertorima

The nitrogen belongs to elements which have significant impact in steel mechanical properties. The influences of individual elements on the properties of solution of nitrogen in the metal bath, on the process of nitrogen dissolution in connection with decarburisation process and also influences of some important factors on the possibilities of nitrogen regulation during the refining period were investigated in this work. The path for production of steel with regulated nitrogen content relies on the combination of knowledge of nitrogen thermodynamics, mechanism and kinetics of nitrogen sorption and desorption, together with possibilities of steel melt properties prediction and also with metallurgical actions leading to the control of required chemical composition.Dušik spada u elemente koji značajno djeluju na mehanička svojstva čelika. U radu su istraženi utjecaji pojedinih elemenata na svojstva otapanja dušika u metalnoj kupci, proces izdvajanja dušika u vezi s procesom odugljičenja a također utjecaji nekih važnih faktora na mogućnost reguliranja dušika tokom perioda rafinacije. Put proizvodnje čelika s reguliranim sadržajem dušika oslanja se na kombiniranje znanja termodinamike dušika, mehanizma i kinetike sorpcije i desorpcije dušika, zajedno s mogućnošću predviđanja svojstava čelične taline, a također s metalurškim djelovanjem koje vodi kontroli zahtijevanog kemijskog sastava
