what is direct reduced iron dri definition and meaningiron sponge

Direct-reduced iron (DRI), also called sponge iron, [1] is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H 2) and carbon monoxide (CO) which acts as reducing agent. Direct-reduced iron (DRI), also called sponge iron, [1] is produced from the direct reduction of iron ore (in the form of lumps, pellets or fines) to iron by a learn more Direct Reduced Iron (DRI) is created by heating iron ore in a steel shaft with natural gas, below the melting point.

For fast direct quantification X-ray diffraction (XRD) is the main tool for fast direct quantification of iron phases in raw ores, sinter, direct reduced iron (DRI) or sponge iron, steel and slag. XRD analysis removes the need for slow, labor-intensive and operator-dependent wet-chemical techniques.

Direct reduced iron (DRI) is a high-quality metal product obtained from iron ore and it is used as raw material in electric arc furnaces, blast furnaces, and in other more recent steelmaking processes [2]. 2. Total DRI Output in the World With the output of approx

In the search for a pure, available iron source, steelmakers are focusing their attention on Directly Reduced Iron (DRI). This material is produced by the reaction of a low gangue iron ore with a hydrocarbonaceous substance. Commercially, DRI is generated in four different reactors: shaft (moving-bed), rotary kiln, fluidized bed, and retort (fixed-bed). Annual worldwide production capacity

Direct reduced iron Wikipedia Directreduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron Reduced iron derives its name from the chemical change that iron ore forms of iron ore (sized ore, concentrates, pellets, mill scale

Understanding the different direct reduced iron products

DRI – Direct reduced iron Normally in the form of sponge pellets or lumps varying between 6 and 25mm nominal diameter, but often 8 to 12mm diameter. The IMO BC Code classes this product as "a material that is hazardous only when in bulk" (MHB).

Sponge Iron/ Direct Reduced Iron(DRI)/ Hot Briquetted Iron(HBI) : • Direct Reduced Iron(DRI): Solid metallic iron product obtained upon Direct Reduction of high grade iron ore in solid state itself without being converted into liquid form like that in Blast Furnace.

Sponge iron A metallic product made by direct reduction of iron, via the removal of oxygen from iron ore. Sponge iron is also known as DRI, or direct reduced iron Slab Semi-finished steel product - the main intermediate material in the production of flat rolled steel.

2018/12/1Iron ore is pre-heated and fed into a reduction shaft, where it is converted to direct reduced iron (DRI) and further compacted to hot briquetted iron (HBI). Hydrogen generated in an electrolysis unit is pre-heated in a condenser before being supplied to the shaft where it acts as the reducing agent.

the development of direct reduced iron (DRI), also called sponge iron. Defining DRI 'Reduced iron' derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in the presence of hydrocarbon-rich gasses.

Direct reduced iron that has been processed into briquettes. Instead of using a blast furnace, the oxygen is removed from the ore using natural gas and results in a substance that is 90%–92% iron. Because DRI may spontaneously combust during transportation, HBI is preferred when the metallic material must be stored or moved.

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction.

Fundamental Studies Related to Gaseous Reduction of Iron Oxide

The product of the DR pr ocess is a highly porous solid iron (sponge iron or DRI). The metallization degrees of DRI vary between 90 and 95% and the products contain carbon with amounts between 0.5 and 4%, depending on the process. Due to large surface

Direct reduced iron (DRI) is a high-quality metal product obtained from iron ore and it is used as raw material in electric arc furnaces, blast furnaces, and in other more recent steelmaking processes [2]. 2. Total DRI Output in the World With the output of approx

CAUTION — Direct reduced iron (DRI) and, in some cases, hot briquetted iron (HBI), for example, with low density or high fines content, may react with water and air to produce hydrogen and heat. The heat produced may cause ignition.

Direct Reduced Iron (DRI): Solid metallic iron product obtained upon Direct Reduction of high grade iron ore in solid state itself without being converted into liquid form like that in Blast Furnace. Sponge Iron (SI): DRI is also known as Sponge Iron because of its spongy micro structure.
