steel research international, EarlyView.The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

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 ...

Steelmaking. Recycle of Steelmaking Waste in Arc Furnace.
DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1999 Minimization and utilization of wastes is one of the most important subject in manufacturing industries today. Daido Steel developed several technologies to utilize wastes so that the reusing and recycling ratio of steelmaking slag, used refractory, EAF dust and stainless steel dust becomes higher.

Influence of Competitive C–P Segregation on Austenite Grain Growth in Iron Alloys
steel research international, EarlyView.This study investigates how carbon influences phosphorus‐induced solute drag effects during isothermal annealing of austenite grain growth in Fe–C–P alloys. Using in situ high‐temperature laser scanning confocal microscopy and density functional theory simulations, it demonstrates that carbon above a critical temperature significantly reduces P ...
