Aug 15, 2015 · the idea of the process of how to make sponge iron from iron ore is basically to add coal to remove oxygen from iron by adding non coking coal and to remove sulfur by adding lime stone, the iron ore and coal are crushed in crushers and screened to the recommended sizes (5mm mm), then mixed and heated to degrees centigrade s, the mixture is treated in .

Jun 02, 2021 · Steelmaking requires stripping oxygen from iron ore to produce pure iron metal. In traditional steelmaking, this is done using coal or natural gas in a process that releases CO₂.

Aug 07, 2016 · Most of the plants in India use DRI process—a solid state direct reduction process by which iron ore is reduced to sponge without phase change. Raw material mixiron ore, dolomite and coal are fed to one end of rotary Kiln as well as some fine coal also fed from discharge end and product sponge iron along with char is taken out from the other ...

Pig iron is typically produced from iron ore and coking coal (aka coke) in a blast furnace (BF) and DRI is produced in a direct reduced iron plant from iron ore (no coking coal) and hydrogen. Some steel plants operate only one type of production route (typically either BFBOF or DRIEAF), but some operate multiple different production routes.

Sponge iron making is a process in which iron ore lumps (typically 5mm18mm size) are tumbled with a 'select' grade of ironcoking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise in finished product bunkers prior to dispatch.

With such dimension of notion WE in our Sponge Iron Manufacturing process through 4 Kilns (1 * 350T and 3 * 500T) laid up the best DRI making process of India. It is Coal Fuel based DRI. Coal based Spongeiron is a metallic product produced through direct reduction of iron ore in the solid state .As such it is also known as Direct Reduced Iron ...

It is called sponge iron, and the Bureau of Mines has decided to risk 500,000 in hurryup development of the hitherto unpractical process by which it is made. To make sponge iron, ore is not smelted. It is mixed with pulverized coal (natural gas can also be used) and coke, then fed to a large rotary kiln.

Sep 24, 2019 · The coke is mixed with iron ore and limestone to make molten iron, which is then further treated and heated to make steel. Generalized diagram showing how steel is made. In the steelmaking process, coke is used in the blast furnace as a (1) fuel to produce added heat; (2) chemicalreducing agent for the reduction of iron oxides; and (3) as a ...

Nov 09, 2014 · ROTARY COOLER The product is conveyed to the product separation and storage building The product is Sponge iron and char Place that spraying a controlled amount of water directly into hot solids and by spraying additional water outside the cooler shell. 12. SCREENING + 10 mm 310 mm 3 mm. 13.

Iron ore can be upgraded to a higher iron ore content through beneficiation This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being ...

Incorporated in the year 1995, we are the best iron mining company in India. Our products include sponge iron, iron ore, pig iron, iron ballets, etc. Our company is a pioneer in taking an effective step in pollution control and environmental sustainability. Know more.

Abstract A survey is made on a typical coal based Indian sponge iron plant of capacity 500t/d in order to identify the largest energy losses and find ways to increase the efficiency. The required data are obtained by measurements or taken from production industries. The process efficiency is about %. The energy balances of the process show that the gap between theoretical .

Sponge Iron (or Direct Reduced Iron (DRI)) This is produced from iron ore and is used in the manufacture of steel. It involves heating the iron ore at low temperatures without allowing it to come in contact with air. It is, therefore, important to allow the piles of sponge iron to be weathered before shipping so that its temperature drops.

High Quality Sponge Iron Powder Direct reduced iron/Sponge Iron Introduction of Sponge Iron Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen ...

Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves. The best time to collect iron ore is in the winter because the ocean is more active. Active waves separate the black, magnetic sand from lighter silica sand. This magnetic sand is an iron ore called magnetite, which when combined with carbon ...

May 10, 2018 · As a result, this type of iron ore ore must be concentrated before it can be used to produce steel. In other words magnetite ore requires more treatment than hematite ore wich must undergo only a simple crushing, screening and blending process before being shipped off .

In 2020, we produced around 280 million tonnes of iron ore. That's enough to make the steel for more than 3,300 Sydney Harbour Bridges. Our new South Flank mine in Western Australia will see its first production in 2021 and become one of the world's largest iron ore operations, producing highquality iron ore for around 25 years.

Sponge Iron. Directreduced iron(DRI), also known as sponge iron is produced from direct reduction of iron ore(in the form of lumps, pellets, or fines) to iron by a reducing gas or elementary carbon produced from natural gas or coal. Many ores are suitable for direct reduction.

Study on Utilisation Coal Fines generated in Sponge Iron Making through Pelletisation Ram Pravesh Bhagat Department of Fuel Mineral Engineering Indian School of Mines Dhanbad 826 004 email: rampravesh1954 ABSTRACT The present study has been made to utilise the coal chars generated in the rotary kiln / certain shaft based DR process through the .

Sponge iron or direct reduced iron (DRI) is used in producing semifinished steel items, ingots and billets, which are further used to make various finished steel items. Coal is a key raw material used to produce sponge iron. "The production is coming down.

Sponge iron produced by direct reduction is melted in an electric arc furnace, in which a pool of liquid metal is maintained. To ensure that liquid carboncontaining iron for forming the pool is available in adequate quantities and that the process can be carried out with the highest possible economy, the sponge iron is reacted in an electric arc furnace on a bath of liquid carbon .

Aug 30, 2013 · The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be. fed directly into iron making blast furnaces. Iron ore is the. raw material used to make pig iron, which is one of the. main raw materials to make steel. 98% of the mined iron. ore is used to make steel.[1]
