Use of Bentonite and Organic Binders in the Briquetting of Particulate Residues from the Midrex Process for Improving the Thermal Stability and Reducibility of the Briquettes [PDF]
Steel Research International, 2021 With the aim of achieving sufficient reducibility and thermal stability of briquettes for reuse as feedstock in the Midrex direct reduction process, a defined mixture of residues from the Midrex process is briquetted with an organic binder and bentonite. In the first step, briquetting tests are conducted to investigate the influence of water and binder

Behavior of Extrusion Briquettes (Brex) in Midrex Reactors. Part 1
Metallurgist, 2015Results are presented from cage tests of the metallization of extrusion briquettes (brex) in an industrial Midrex reactor. The brex are made by the stiff vacuum extrusion of dispersed iron-bearing waste products with the use of different binder materials.

MODEL-BASED ENERGY ANALYSIS OF AN INTEGRATED MIDREX-BASED IRON/STEEL PLANT
Chemical Engineering Communications, 2014This article presents modeling and simulations of an integrated plant for the production of steel using the direct reduced iron (DRI)/electric arc furnace (EAF) route. In a previous work (Alhumaizi et al., 2012), a comprehensive mathematical model of an iron plant based on MIDREX technology was developed, validated, and simulated.

Optimization of Midrex Direct Reduced Iron Use in Ore‐Based Steelmaking
steel research international, 2014Iron and steel industry contributes by more than 5% to the global anthropogenic CO2 emissions, so new ways to reduce the emissions in this industrial sector must be found. In order to facilitate a transition to more sustainable production concepts, economic factors must be considered.
