Abstract:

Various methods of liquefaction of steel are used all over the world; steelmaking in converter furnaces and steelmaking in electric arc furnaces and induction furnaces are two main areas among them. Steel production in electric furnaces is divided into steel production in induction furnace and electric arc furnace. In many countries, induction furnace liquefaction is common and is used mostly in private production enterprises. There is a large amount of literature on electric arc furnace steelmaking, and less information on induction furnace steelmaking. To study any process; the energy balanc

From the point of view of the synthesis of control influences, arc steelmaking furnaces are complex nonlinear objects with strongly expressed mutual influences.

This dependence is preserved in transient modes. In order to identify arc lengths from the phase currents, it is proposed to use an approach based on the theory

Abstract:

There are two main kinds of slag in modern steelmaking industry: the electric arc furnace slag (the EAF slag) which is produced in the manufacture of crude steel by the electric arc furnace process and the ladle furnace basic slag (the LF slag) which is produced at the final stages of steelmaking, when the steel is desulfurized in the transport ladle, during what is generally known as the secondary metallurgy process.

PurposeThe purpose of this paper is to present a 3D finite element model of the electromagnetic fields in an AC three‐phase electric arc furnace (EAF). The model includes the electrodes, arcs, and molten bath.Design/methodology/approachThe electromagnetic field in terms of time in AC arc is also modeled, utilizing a 3D finite element method (3D FEM). The arc is supposed to be an electro‐thermal unit with electrical power as input and thermal power as output. The average Joule power, calculated during the transient electromagnetic analysis of the AC arc furnace, can be used as a thermal source

Pavement maintenance is an essential activity for maintaining the quality of the pavements. It is common for the ageing pavement to present problems of friction, so a proper solution must be provided. In this work, electric arc furnace slags are incorporated in slurry surfacing to provide adequate friction with this technique. The electric arc furnace slag was studied with physical, chemical, and mechanical tests to evaluate its suitability in the formation of the bituminous mixture. At the same time, different groups of samples were made with increasing percentages of bitumen emulsion and sla

This study examines the carbon and energy intensity of steel production in Poland, with a particular focus on the Blast Furnace–Basic Oxygen Furnace (BF-BOF) process. Given its dominant role in the industry, decarbonizing this process is crucial for achieving the “Net Zero” targets outlined in the Strategy 2050 climate policy. The transition toward deep decarbonization presents significant technological challenges, primarily the shift from high-carbon BF-BOF technology to low-carbon alternatives, such as hydrogen-based direct reduction iron in Electric Arc Furnaces (H2-DRI-EAF—Hydrogen-Based D

Stochastic performance of an electric arc furnace (EAF) has drawn researcher’s attention due to power quality problems introduced by EAF operation. In this paper, Electric arc furnace is modeled to investigate power quality problems. Voltage flicker, harmonics and inter-harmonics are the main power quality disturbances that arise in the electrical network as a result of arc furnace operation due to the non-linear nature of EAF. A time domain model is derived to study the behavior in various operating conditions (melting and refining). The characteristic modeling of an EAF is carried out in MAT

The actual problem of mineral resources depletion in ferrous metallurgy can be effectively solved by complex reuse of technogenic waste. That waste is mostly presented by EAF (electric arc furnace) slag and LF (ladle furnace) slag. These two kinds of slag have no complex full utilization. The residues of slag are going to the dump and then the slag dump locations pollute the environment. However, the residues of EAF and LF slag can be transformed into the valuable industrial product by interaction of the slag components.
