AISI Direct Steelmaking Program [PDF]

, 1991
Pilot plant trials with the horizontal vessel were completed. Design of a third pressurized vessel and an offgas cleaning and tempering system was completed. Installation is now underway. A basic study and a pre-engineering design of a 350,000-metric ton/y demonstration plant were completed, and efforts are underway to develop such a demonstration ...

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior

steel research international, EarlyView.
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Phoenix-Lance steelmaking [PDF]

JOM, 1959
Here is an interesting new steelmaking technique being developed in Germany for the production of open-hearth quality steels from high-phosphorus pig irons. It utilizes the classical basic-bessemer converter with top-blown oxygen, and has the advantages of early phosphorus removal and, consequently, less nitrogen pick-up in the final steel.

Reduction, Softening, and Melting Characteristics of Mill Scale‐Based Briquettes for Blast Furnace Ironmaking

steel research international, EarlyView.
The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...

Dissolution Rate of Various Limes into Steelmaking Slag

High Temperature Materials and Processes, 2013
In the steelmaking process, various solid oxides such as lime and dolomite are used as flux. It is well known that the dissolution rate of these oxides into the molten slag has an important role to increase the reaction rate between the steel and slag ...

A Thermodynamic‐Kinetic Model for Basic Oxygen Furnace Tapping: Improved Prediction of Phosphorus and Steel‐Slag Evolution

steel research international, EarlyView.
This study develops a thermodynamic–kinetic model for basic oxygen furnace tapping and validates its accuracy under near‐equilibrium and far‐from‐equilibrium initial conditions. Comparison with a reference model demonstrates its broader applicability. The model further reveals the evolution of key steel and slag components, providing new transparency ...

Deformation behavior of typical inclusions in GCr15 during hot rolling process [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy
Non-metallic inclusions have a considerable influence on the lifespan of bearing steel. Studying the deformation behavior of these inclusions during the rolling process is crucial for controlling their shape and size in production.

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.

Stigma Management within and between Levels

Journal of Management Studies, EarlyView.
Abstract We respond to recent calls to connect our understanding of stigma across and between levels of analysis by investigating how stigma management strategies to the same stigma vary and relate in nested industry, organizational, and individual actors.
