Jun 15, 2024 · Electric Arc Furnaces (EAFs) play a pivotal part in the steel industry, offering a versatile of producing high-quality steel. This paper conducts an in-depth examination of the EAF, along with exploring mathematical modeling and optimization techniques pertinent to this furnace.

The electric arc furnace (EAF) is a highly energy intensive process used to convert scrap metal into molten steel. The aim of this research is to develop a dynamic model of an industrial EAF process, and investigate its application for optimal EAF operation. This work has three main contributions; the rst contribution is developing

Specific electrical energy demand and electrode graphite consumption represent the most important contribution to conversion costs. Maximising yield from ferrous raw materials, oxygen, carbon, and alloys as well as minimising energy costs are top priority.

A model can be developed to describe specific phenomena that characterize only certain phases or parts of a process or, often using several submodels and zones, a complete process such as the EAF from charging to tapping with the outside of the furnace forming the system boundary.

A base model of the EAF has been developed to assess basic features like flow patterns, wall shear, temperature distribution and heat transfer, as well as the efficiency in mixing of trace species. The stirrer forces can be in the forward direction (towards the EBT region), or in the reverse direction, or it can be

Feb 18, 2022 · The model addresses all the main phenomena occurring during the EAF process using empirical relations linked to process conditions: charge heating by arc and burners, scrap melting, C and O2 injection, slag-metal-gas reactions and post-combustion.

The EAF model consists of all three mechanisms of heat transfer: conduction, convection and radiation. Conduction occurs between zones that are in direct contact with one another. Convection occurs between the gas zone and the surrounding zones.

Sep 16, 2022 · This paper presents a comprehensive model of an industrial electric arc furnace (EAF) that is based upon several rigorous first-principles submodels of the heat exchange in the EAF and practical experience from an industrial melt shop.

Jun 30, 2016 · The paper presents a comprehensive electric arc furnace (EAF) model, developed for simulation and model-based control of the EAF processes. The model consists of three sub models, i.e., (i) arc model; (ii) chemical and slag model; and (iii) heat-transfer model.

Market demands on steel quality, price and production times dictate an introduction of technological innovations regarding the electric arc furnace (EAF) steelmaking. A developing field with significant potential is related to the advanced software support of the EAF operation, combining monitoring and proper control of the EAF.
