DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore .
Mar 11, 2016· The presentation describes different processes for the production of direct reduced iron.
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.
Sponge iron provides the base feedstock for all iron-based, self-lubricating bearings and still accounts for around 30% of iron powder usage in PM structural parts. Solid state reduction is also used for the production of refractory metal powders, using hydrogen as the reducing agent, and for the production of specialist iron powders by the ...
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).

Dietary supplements containing iron were the first products to be manufactured by company founder Dr. Paul Lohmann ® at the turn of the 20 th century. The base material used was iron powder, which was obtained by the process of reducing iron oxide with hydrogen. Back then, "ferrum oxydatum cum Saccharo" (iron sugar) and iron peptonate, for example, were available from pharmacies in the form ...
from the DRI production plant) will be reduced by 50 - 100 kg.) 3. Increase in the productivity of blast furnaces The productivity of a blast furnace increased with charging DRI with large metallic iron content to it. (When 100 kg of DRI is used for the production of 1 ton of molten iron, the production of molten iron increases by 10 - 15 %.) 4.
Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.. Powder metallurgy is also used to make unique materials impossible to get from melting or ...
We manufacture Iron Powder Electrolytic using latest technology to ensure its premium quality. It finds application in making welding electrodes, cutting tubes, flame cutting & scarfing, abrasive wheel, frictional material, metal pastes in powder metallurgy and for removing iron from flour and food products.
Iron powder is produced in many different grades for varieties of applications. High purity fine iron powders are used to manufacture sintered components, soft magnetic components, brazing, iron fortification, friction products, printing, surface coating, welding, chemistry and polymer filtrations. Iron powder products are classified by purity, production method, grain and density.

Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned.Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth's crust, and it is the ...

Due to the development of additive manufacturing processes, the metal powder industry has grown significantly in recent years. To achieve physical properties of powder material that meets strict metallurgical requirements for further processing, especially for the additive manufacturing industry, the use of high-quality specialty gases becomes indispensable in many ways.
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. The ...
To produce 1 ton of DRI, we use 1.35 tons of iron ore raw materials, 400 m3 of natural gas and spend extra US$50-70. To produce 1 ton of pig iron, we use 1.5 tons of iron ore raw materials, 0.5 tons of coke and and spend extra US$50-70.

The Metal Powder Industries Federation is a federation of six trade associations representing various aspects of powder metallurgy (PM), metal powders, and particulate materials. Our mission is to advance the interests of the metal powder producing and consuming industries.
Overview. Hot Briquetted Iron (HBI) is a premium form of DRI that has been compacted at a temperature greater than 650° C at time of compaction and has a density greater than 5,000 kilograms per cubic metre (5,000 kg/m 3).. HBI was developed as a product in order to overcome the problems associated with shipping and handling of DRI - due to the process of compaction it is very much less ...
