摘要：The article presents the technological advances and modernizations carried out at national and / or world level in the field of increasing the electric steel quality. In this context, conventional complex steel processing methods are analyzed outside the electric arc furnace, in order to increase the electric steel quality. Special non-conventional procedures for the production of quality steels are also presented. The progress achieved in the field of steel production, mainly aimed at increasing productivity and quality, had as a basic premise the "secondary metallurgy" or the treatment of the metal outside the primary production aggregate (furnace or converter). This concept involves transforming the furnace or the converter into a specialized fast-melting aggregate, the rest of the processes specific to advanced steel refining being carried out in pots (which is why the "pot metallurgy" denomination is also used). We will also present in the article a revolutionary concept for the steel production in the electric arc furnace, a procedure which is the subject of a patent application belonging to the authors of this article, applying the pyramid effect for the steel production in the electric arc furnace.
