What is Direct Reduced Iron? (with picture)

Jul 28 2019Direct reduced iron (DRI) is a type of alternative iron made by heating iron ore so that the oxygen and carbon burns off while the temperature is kept below iron's melting point Direct-reduced iron is also known as sponge iron and is sold as briquettes lumps or pellets Get price

Image

Direct Reduced Iron (DRI)

Direct-reduced iron (DRI) also called sponge iron 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 (H2) and carbon monoxide (CO) which acts as reducing agent Get price

What is direct reduced iron (DRI)? definition and meaning

Definition of direct reduced iron (DRI) Alternative iron source produced by heating an iron ore (generally having 65 to 70 percent iron) at a temperature high enough to burn off its carbon and oxygen content (a process called reduction) but Get price

Direct reduced iron process

Direct reduced iron (DRI) process In addition to the process route via the blast furnace process there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route) The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure Get price

Iron and Steelmaking

Reduction of iron oxides by carbon 37 reduction of magnetite and wstite see Figure below Indirect reduction is carried out at temperatures to about 800 C in the range of 800 to 1100 C both types of reduction take place and above the temperature of 1100 C only direct reduction occurs Get price

Image

The increasing role of direct reduced iron in global

'Direct reduction' refers to processes which reduce iron oxides to metallic iron below the melting point of iron The product of such solid state processes are called direct reduced iron (DRI) whereas the product of the blast furnace is referred to as hot metal in the molten state or pig iron in the solidified form Get price

Direct Reduced Iron (DRI) Production Plant

A direct reduced iron (DRI) production plant is a shaft reduction furnace to produce DRI with large metal iron content by directly reducing iron ore (or iron ore pellets) with reducing gases While the produced DRI is mainly used as the raw material of electric steelmaking it is also used asGet price

Image

Direct Reduced Iron

Direct Reduced Iron (DRI) also known as Sponge Iron offers an alternative steel production route to BF-BOF and Scrap-EAF routes In DRI iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction DRI can then be transformed to steel in electric arc furnaces Get price

Image

Direct Reduced Iron (DRI)

Use of Direct Reduced Iron (DRI) in the Electric Arc Furnace (EAF) for Steelmaking Shipping and handling of DRI Being a highly reduced material DRI has a tendency to re-oxidise an exothermic reaction Thus without appropriate precautions being taken in its handling transport and storage there is a risk of self-heating and fires Get price
