Oct 17 2017Figure 3 Direct iron reduction shaft furnace Source MIDREX Direct iron reduction processes reduce iron ore to sponge iron without a molten metal step Direct iron reduction or sponge iron production was practiced in ancient times The sponge iron was then hammered to remove impurities and produce iron weapons and tools The Group's steel businesses are involved in iron and steel making rolling of flat and long products and downstream manufacturing of various steel products including steel service centres It operates Megasteel Malaysia's first and only integrated flat steel mill producing hot rolled and cold rolled coils

Rashmi Metaliks Limited

It is the main substitute for steel form known as Hat Briquette Iron (HBI) It is the main substitute for steel scrap in steel making Sponge iron production requires small quantity of energy as no melting process is involved The DRI assumed nick name Sponge Iron due to its appearance of sponge

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

Typically the Integrated Steel Plants(ISPs) use medium/High grade Iron Ore whereas the Sponge Iron plants require only High Grade iron ore preferably with +67% Fe Lumpy/Fine Ore Iron Ore is traded in lumps (i e sized ore) or in fines Production/availability of lumps is limited by virtue of the natural occurrence and also because of

scrap or sponge iron The process used for the manufacturing of iron steel has a bearing on the cost of production the quality of the steel produced The Iron Making process The first step in the steel making process is producing iron from iron ore The process is called the iron-making process Three different methods can

Sponge Iron Plant Technology – MIDREX Gas based Commissioned -1994 Original capacity-1 0 MTPA World's first mega module DRI plant Current capacity -1 6 MTPA Modifications carried out in 2005 Successfully operated with Iron ore Lump in feed mix Achieved annual production


Direct Reduced Iron (DRI) Production Plant

u 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 u While the produced DRI is mainly used as the raw material of electric steelmaking it is also used as

The process where the aluminium is shaped to its required form This process is used for making the vast majority of aluminium products from spectacle frames telephone bodies aeroplane fuselages or spaceship bodies The malleability of aluminium means it can be easily rolled into thin sheets

Mar 01 2019The pure titanium sponge is then turned into a titanium alloy for commercial use with the help of an electrode arc furnace At this point the sponge is mixed with various alloy additions and scrap metal The exact proportion of sponge to alloy material is formulated in a lab before production

Salman Al-Johar Sponge Iron Factory this factory will produce the sponge iron and the raw material come from the pellet from the first factory and the final product the sponge iron it will be the raw material for the melting plant The capacity of this plant is 200 000 ton yearly and the production of

Iron ore as mined is a combination of iron with oxygen and various other unwanted substances generally known as gangue The first metallurgical step is to reduce iron ore to metallic iron a process which is mostly carried out in a blast furnace using coke as both a fuel and reducing agent

Study on Accretion Formation on DRI kiln during spong iron production Chandrashekhar shrivas Himanshu shrivas Abstract---Today is an era of competition and contrary to this the Iron and steel industries are also suffering from the same One of the major challenges for sponge iron plant is the Accretion formation Through this

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

H2S scavenger

The process of removing H 2 S is known as gas sweetening by either iron sponge H 2 S scrubbers (forming iron sulfide) or chemical scavengers Typical H 2 S scavengers used in the oilfield are amine based chemicals [1] They can be roughly categorized into regenerative and non-regenerative H 2

Sphagnum moss also possesses natural bacterial fighting abilities and was used in World War I as a wound dressing Sphagnum moss is simple to use and beneficial for potted plants as a liner as it acts like a sponge absorbing and retaining moisture while keeping its natural acidity

been in contact with the oil and gas production stream during the removal of produced water or other contaminants from the product As an example a spent paraffin solvent used in a well is an exempt oil and gas waste when it is recovered from the wellbore If that same solvent is used to degrease

The sponge iron is mainly used for steel production in electric arc furnaces Two steps are required with the smelting reduction method First the ore is reduced to sponge iron and this is then converted to a blast-furnace-like form of hot metal through the use of coal and oxygen

Mar 16 2013DRI Production process Due to it the DRI is also known as sponge iron HBI is produced by compacting DRI under very high pressure at temperatures in excess of 650 deg C This closes many of the pores and limits the contact area which is available for reaction with air It also increases its thermal conductivity
