Developments in electric arc furnace steelmaking
, 2001 In recent years, the growth of EAF steelmaking and the corresponding push for improved productivity and lower energy usage, has seen a blurring of the boundary between oxygen and electric steelmaking and a departure from the pure batch processing ...

Study of Current Steelmaking Practices to Evaluate the Viability of Continuous Steelmaking
, 2004 The viability of continuous steelmaking under current steelmaking practices is discussed. There are several differences between the steelmaking practices in a conventional meltshop and the expected practices for continuous steelmaking meltshop. The batch

Effect of Flow Rate and Partial Pressure of Oxygen on Desulfurization of KR Slag
MetalsKR (Kanbara Reaction) desulfurization slag is a solid waste that is not sufficiently utilized. This is because the KR desulfurization slag contains 1–2.5% sulfur, which is directly used in steel smelting to increase the sulfur content in molten steel ...

Sustainable Development, EarlyView.ABSTRACT The large multinational metalworking industry has increasingly adopted micro‐level circular economy (MLCE) practices; however, the extent to which these initiatives translate into sustainable performance remains insufficiently understood. This study examines the relationship between MLCE and economic, environmental, and social performance ...

Raw material assessment for electric arc furnace steelmaking
, 2015 In this study, steelmaking in an Electric Arc Furnace, EAF, using two types of recycled scrap with different levels of tramp-Cu and different prices, is compared to steelmaking where part of the burden is changed to a virgin iron source.

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage
steel research international, EarlyView.This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

Modeling of BOF steelmaking based on the data-driven approach
, 2013 This paper is concerned with the modeling of both endpoint temperature and carbon content for BOF steelmaking. First, a linear regression predictive model is constructed based on the linear regression analysis method.

steel research international, EarlyView.The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

A Novel Approach to Energy Management in Electric Steelworks
steel research international, EarlyView.Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.

The Development of an Optimized Impact Pad for a Six-Strand Tundish Using CFD Simulations
Applied SciencesThe behavior of molten steel within a tundish plays a crucial role in achieving uniform temperature and chemical composition, enhancing the removal efficiency of non-metallic inclusions, and reducing the wear of refractory linings.
