Impact of selected tramp elements in medium carbon steels on the deformation behavior of non-metallic inclusions and phase transformations Open
Scrap recycling is one of the major pillars of the steel industry's green transformation. It is important, however, to consider the available scrap's tramp element levels. While non-metallic inclusions (NMIs) and tramp elements are both co…

Influence of Tramp Elements on Surface Properties of Liquid Medium‐Carbon Steels Open
The transformation of the steel industry is inevitably linked to increased recycling rates of steel. However, end‐of‐life scrap is often contaminated with tramp elements like copper, molybdenum, and tin and while their influence on mechani…

Bacterial Metal Accumulation as a Strategy for Waste Recycling Management Open
Sustainable mechanisms for efficient and circular metal recycling have yet to be uncovered. In this study, the metal recycling potential of seven metal-resistant bacterial species (Deinococcus radiodurans, Deinococcus aerius, Bacillus coag…

On the Change in Hydrogen Diffusion and Trapping Behaviour of Pearlitic Rail Steel at Different Stages of Production Open
To avoid hydrogen flaking in rail production, it is of crucial importance to understand the differences in hydrogen diffusion and trapping between different production steps. Therefore, as-cast unfinished material was compared with two fin…

Thermoacidophilic Bioleaching of Industrial Metallic Steel Waste Product Open
The continuous deposition of hazardous metalliferous wastes derived from industrial steelmaking processes will lead to space shortages while valuable raw metals are being depleted. Currently, these landfilled waste products pose a rich res…

Effect of the Al<sub>2</sub>O<sub>3</sub> Content in the Slag on the Remelting Behavior of a Bearing Steel Open
The service life of roller bearings strongly depends on nonmetallic inclusions (NMIs). Therefore, these steels request highest metallurgical standards in their production. To determine the effect of the Al 2 O 3 content and a protective at…

Effect of the Al2O3 Content in the Slag on the Chemical Reactions and Nonmetallic Inclusions during Electroslag Remelting Open
The service life of roller bearings is extremely sensitive to large and hard nonmetallic inclusions (NMIs), requesting the highest standards in their production. To determine the metallurgical possibilities, the effect of Al 2 O 3 contents…

Diffusive Steel Scrap Melting in Carbon-Saturated Hot Metal—Phenomenological Investigation at the Solid–Liquid Interface Open
The oxygen steelmaking process in a Linz-Donawitz (LD) converter is responsible for more than 70% of annual crude steel production. Optimization of the process control and numerical simulation of the LD converter are some of the current ch…

Evaluation of the Influences of Scrap Melting and Dissolution during Dynamic Linz–Donawitz (LD) Converter Modelling Open
The Linz–Donawitz (LD) converter is still the dominant process for converting hot metal into crude steel with the help of technically pure oxygen. Beside hot metal, scrap is the most important charging material which acts as an additional …

Dissolution of Scrap in Hot Metal under Linz–Donawitz (LD) Steelmaking Conditions Open
One of the main charging materials of the Linz–Donawitz oxygen steelmaking process (LD) is scrap. Scrap acts as a coolant for the exothermic reactions inside the LD vessel and as an iron source in addition to hot metal. The optimization of…
