Researches Regarding the Elements Loss through Vaporization during the Elaboration Process in LD Converter
Keywords:

Abstract
The paper presents a series of researches regarding the vaporization of the component elements of the metallic bath and slag during refining in LD converter. Also, the main factors which influence the vaporization process during steel making in LD converter are studied: the converter atmosphere; the carbon content of the metallic bath; the speed of the oxygen jet; the temperature of the metallic bath; the blowing diagram. Based on these researches we sought to obtain a technology of steel making in LD converter so that the percentage of losses by vaporization is minimum.
