Over the past few decades, steelmaking has reached its zenith in terms of annual productivity, and relevant processes have been developed over time to produce steel with maximum efficiency in a shorter time. One of the prominent steelmaking practices used extensively in contemporary industries is the Conarc Steelmaking Practice, which involves the use of electrical and chemical Energy to carry out melting and decarburization in respective shells. This article reviews the factors that affect the energy consumption in Conarc furnaces and provides insight into the technologies developed to alleviate energy consumption and make the steelmaking process optimal in terms of energy consumption and requirement. This article also accentuates relevant systems and melting practices for the raw materials, which can be utilized in the Conarc Steelmaking practice to make the entire process less energy-intensive. Oxygen-enhanced combustion and thermophotovoltaic systems can alleviate energy consumption substantially while maintaining steel quality at the same time, as discussed in the paper. Additionally, some mathematical models have been discussed that facilitate in formulating an energy optimal and financial steelmaking process.

Abstract. The spatial organization of enterprises is of great importance for the metallic materials industry (metallurgy), given the diversity and complexity of the technological processes and the related equipment. In an enterprise from the metallic materials industry, there may be sections for: production, casting, forging, mechanical (hot and / or cold) processing, assembly etc. for the different stages of the technological process related to the products to be made. The article presents theoretical and practical elements regarding the management of the spatial organization of enterprises in the metallic materials industry. The principles and methods of spatial organization are presented and analyzed. These principles and methods are based on the biunivocal relation between the functional and constructive changes related to the technologies and equipment (machinery, aggregates) specific to the metallic material industry. Prescribing (establishing) the objective function (OF) of the technological processes modeling system in the metallic materials industry is based on the qualitative -economic analysis of these processes.

“…Usually, metal processing in the pot takes place in a neutral or reducing atmosphere and aims to achieve the following objectives (separately or together, [1][2]): -homogenizing the temperature and chemical composition of the steel; -alloying of the steel in a narrow area of the chemical composition; -steel deoxidation; -reduction of the non-metallic inclusions content; -desulphurization; -reduction of gases content in the steel ([H], [N]); -reduction of the undesirable additions content; -reaching a prescribed grain size; -correction of the steel temperature to achieve the casting temperature.…”

Management possibilities for increasing the electric steel quality

Abstract. 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.
