Direct reduced iron (DRI) is also known as sponge iron (Hasambeigi et al. 2014 ). This high porous material has a metallization degree in the range 85–95% with a carbon content in the range 0.5–4% depending on the processing route. During the process, the iron oxides are reduced at the solid state.

DRI, primarily appearing as sponge pellets or lumps measuring between 6 and 25mm, often averages between 8 to 12mm. Classified by the IMO BC Code as a substance hazardous in bulk quantities (MHB), it's listed under BC015. Upon exposure to moisture, it's prone to significant overheating, emitting hydrogen gas.

of blast furnaces. Rectangular six in line furnace can produce more than 1.25 Mt/y of hot metal, while Outotec circular AC smelting furnaces are limited. Several DRI Smelting Furnaces can be combined using joint facilities and utility areas. For blast furnace grade iron ores, the combination of DRI Smelting Furnace with a direct reduction

Among heavy industrial sectors worldwide, the steel industry ranks first in carbon dioxide (CO 2) emissions.Technologies that produce direct reduced iron (DRI) enable the industry to reduce emissions or even approach net-zero CO 2 emissions for steel production. Herein, comprehensive cradle-to-gate (CTG) life cycle analysis (LCA) …

Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. …

2022 World Direct Reduction Statistics Page 4 9.12.23 Direct Reduced Iron Production I ndia continued its streak as the number one DRI producer worldwide, producing a record 43.55 Mt of DRI – 35.39 Mt in rotary kilns and 8.16 Mt by gas-based processes – an 11.4% increase overall. According to the Sponge Iron Manufacturers

The direct online starter is a basic and simple starter for starting the induction motor. In DOL Starter, we connect the stator winding of the induction motor directly to the three-phase supply voltage. Thus, the stator winding receives full line voltage. The DOL motor starter is suitable for starting small-rating motors because the motor draws ...

1.1 Direct Reduced Iron Direct reduced iron is produced by the reduction of iron ore by carbon monoxide and hydrogen, as illustrated in simplified form in the equations below: Fe 2O 3 + 3CO → 2Fe + 3CO 2. Fe 2O 3 + 3H 2 → 2Fe + 3H 2O . There are several processes for direct reduction of iron ore, principally gas-based shaft furnaces

Direct reduction (DR) is an alternate form of ironmaking that is economic at much smaller scales, generally uses natural gas as reductant instead of coke, and costs considerably less than a blast furnace facility. Worldwide production of Direct Reduced Iron has increased from less than one million tonnes per year in 1971 to over 70 million ...

Analogously, when the magnetite is reduced to wüstite the reaction at the magnetite/wüstite interface can be expressed as: (5) F e 3 O 4 + F e 2 + + 2 e − → 4 F e O In contrast, oxygen atoms must diffuse from the iron/wüstite interface to the iron/gas interface once a dense iron layer forms, Fig. 2 (b) [6, 18].Then, hydrogen reacts with …

The effects of gas composition and the extent of reduction on the compressive strength of direct reduced iron (DRI) were investigated. Gas mixtures containing different proportions of hydrogen, carbon monoxide, water vapor, carbon dioxide and methane were tested. The structure of laboratory and industrial DRI was examined …

1 Introduction. The iron and steel industry as one of the biggest industrial emitters of CO 2 accounts for approximately 30% of the global industrial CO 2 emissions. As set in the Paris Agreement, the emissions of greenhouse gases have to be reduced by 80–95% until 2050 compared with preindustrial levels to keep global warming below 2 °C.

The blast furnace and direct reduction processes have been the major iron production routes for various iron ores (i.e. goethite, hematite, magnetite, maghemite, siderite, etc.) in the past few decades, but the challenges of maintaining the iron and steel-making processes are enormous. The challenges, such as cumbersome production …

In this study, the potential to reduce CO2 emissions from blast furnace processes by using direct reduced iron (DRI) as a pre-reduced input material is examined.
