Investigation of the Reoxidation and Material Behavior of Directly Reduced Pellets and Fines Under Simulated Rail Transport Conditions

steel research international, EarlyView.
The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.

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.

The Influence of the Pretreatment of Tool Steel on the Running‐In Phase of Diamond‐Like Carbon Coatings

steel research international, EarlyView.
The influence of tool steel pretreatment on the running‐in behavior of TiNb‐diamond‐like carbon (DLC) coatings is investigated. Ion etching promotes carbide protrusion and increases coating roughness, while post‐deposition polishing reduces surface asperities.

A Critical Review on Nitrogen Control in the Scrap‐Based Electric Arc Furnace Steelmaking Route to Produce Low‐Nitrogen Steels

steel research international, EarlyView.
In primary electric arc furnace (EAF) steelmaking, carbon boiling removes nitrogen from liquid steel and sustains slag foaming. In 100% scrap‐ or hydrogen direct reduced iron (HDRI)‐based EAF steelmaking, carbon boiling is absent; therefore, carbonaceous material and oxygen injection into the slag is needed to maintain foaming and avoid nitrogen ...
