Plant Treatments of EAF Slag for its Use as Construction Materials

Advanced Materials Research, 2013
At the steel plant of Höganäs Sweden AB, different steel grades were produced using an Electric Arc Furnaces (EAF). The slag tapped by the EAF often disintegrated during cooling. Slag fines from the disintegration are difficult to handle and to use as materials in construction.

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.

Decreasing the Environmental Impact of the Electric Steelmaking Route Through Advanced Modelling Techniques

steel research international, EarlyView.
Ensemble models are adopted to estimate the sterile content of scraps arriving to the scrap yard. Feed‐forward neural networks are exploited to estimate steel composition and temperature after Ladle furnace. The models are validated on data from two steelworks very satisfactory results and are inherently transferable to other steelworks, as they are ...

Usage of BOF Slag and Next Generation EAF Slag in the Cement Industry

Journal of Sustainable Metallurgy
Abstract Two research projects examine the application of slags from today’s and future steel production in the cement industry as reactive binder components. The completed project SlagCEM investigated the recovery of iron from basic oxygen furnace (BOF) slag while simultaneously producing a clinker-like mineral product with good ...

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

steel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

steel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.
