Parametric study of heat transfer in an electric arc furnace and cooling system

Malzeme Üretiminde Siber Güvenlik

“…Electric arc furnaces (EAFs) are one of the common technology used in steel industries and widely used to produce steel by melting recycled scrap steel [23], [24], [31], [45]. The EAF contributes to steelmaking by providing more than 25% of the world's total crude steel production [14].…”

“…It also focuses on these cyber threats in action and analyses how best to achieve successful cyber security in material/metallurgical manufacturing. Sintering systems, arc furnace and induction furnace systems are commonly used in metallurgical or material engineering and in factories [5], [6], [15]- [24], [7], [25]- [31], [8]- [14].…”

Operation optimization of holding furnaces in special casting shops

“…Such solutions can be recognized as successful, however, the models and the IT solutions implemented on them in terms of automation and computer integration are not disclosed by manufacturers. Obviously, simulating the opera tion of the melting and casting system, it is necessary to take into account that the furnaces are energytechnology and heat engineering complexes, regardless of the method of energy supply [10,11]. Their thermal performance and energy capabilities can have a decisive influence on the ISSN 2226-3780 melting quality and the ability to provide consumers with a given amount of melt with the required properties.…”

Stability assessment of 30ХНМЛ steel melting process in electric arc furnaces on the basis of technological audit of serial meltings

“…The problem of assessing the stability of electric arc melting processes is reduced to the choice of evaluation criteria and the possibilities of their application in ac cordance with the level of technological development in a particular production. Typical solutions in this part are the presentation as priority electrical modes of operation of the furnaces as energy technology complexes integrated into the power grid [3,4] or thermal performance [5]. In the first case, the actual modeling and parameter estima tion is replaced by a computer using readymade software packages, for example, in the SIMULINK/MATLAB en vironment [3].…”

“…In the first case, the actual modeling and parameter estima tion is replaced by a computer using readymade software packages, for example, in the SIMULINK/MATLAB en vironment [3]. In the second case, 3D modeling is used to estimate thermal fields, temperature distribution in the furnace depending on the internal geometry, systems for isolating its individual elements and cooling [5]. Such typical approaches are convenient, given the current ca pabilities of software and hardware, but they are focused more on the performance of the metallurgical units them selves, rather than on the products manufactured by them.…”
