DEPHOSPHORIZATION KINETICS FOR REACTION OF BLOATED METAL DROPLETS WITH OXIDIZING SLAG [PDF]

, 2017
Dephosphorization is one of the most important refining reactions in Steelmaking in the Basic Oxygen Furace (BOF). Dephosphorization can only occur by reaction between the metal and the slag and is linked in a rather complex way to the decarburization of

Experimental and Computational Investigation of Slag–Refractory Interactions Under Conditions Relevant to Hydrogen Plasma Smelting Reduction

steel research international, EarlyView.
This study investigates how slag interacts with magnesia–carbon (MgO–C) refractories under conditions relevant to hydrogen plasma smelting reduction. High‐temperature refractory wear tests are combined with thermodynamic modeling to examine refractory dissolution into slag and slag infiltration into the refractory.

Prospects of Eliminating Fluorspar Consumption in a Sustainable Argon‐Oxygen‐Decarburization Process

steel research international, EarlyView.
This study aims at identifying pathways for eliminating fluorspar consumption in the argon‐oxygen‐decarburization (AOD) process. Thermodynamic calculations suggest the feasibility of completely replacing fluorspar with alternative fluxes such as Al2O3, Na2O, K2O, and Li2O of suitable amounts.

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, Volume 97, Issue 8, Page 4126-4137, August 2026.
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 ...
