1.1 blast Furnace slag The slag produced from the blast furnace during production of pig iron is called blast furnace slag. This is a non-metallic product consisting primarily of silicates, alumina-silicates, and calcium-alumina-silicates. The molten slag comprises about 20 per cent by mass of iron production. In

Blast furnace ironmaking is inseparable from the coke source, but the coke resources are getting less and less, but the price is getting higher and higher, the cost of iron making will be higher and higher, and it is likely that one day will meet the depletion of coke resources. 2. The blast furnace ironmaking damages the environment very much. 3.

EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.

Blast furnace slag is a secondary aggregate used widely in construction because of its performance attributes and durability.

Raw Materials: Iron Ore (Haematite), Coke, Limestone and Air. Explanation: Iron Ore, Coke and Limestone are mixed together and fed into the top of the blast furnace. Hot air is blasted into the bottom of the blast furnace; Zone 1. Coke is used as the starting material. It is an impure carbon and it burns in the hot air blast to form carbon dioxide.

Slag from Hope Furnace, Vinton County, Ohio. Several of you recognized this hard shiny material as slag. Though it can look like the mineral obsidian, slag is actually the by-product of the smelting process to obtain metal from raw ore. Metals such as iron, lead, copper and others are found in nature in their impure states, called ores.

Malleable Iron is the purest form of iron available commercially and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe2O3). The Haematite then reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas. Fe 2 O 3 +3C→2Fe+3CO. Limestone then creates the slag.

· The blast furnace Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.

blast furnace, Hot metal, hot metal runner, ladle, lime milk, PCM, Pig iron, skimmer, slag, Torpedo ladle, Handling of Hot Metal in Blast Furnace Iron Making Hot metal (HM) is produced by the reduction of descending ore burden by the ascending reducing gases in a blast furnace (BF). It is liquid in nature and gets collected in the hearth of the BF.

BOS Slag. Process. When molten iron (referred to as "hot metal") from the blast furnace is to be converted into steel, the main tasks are the removal of carbon, silicon and phosphorus. The LD (Linz-Donawitz) process is by far the most widely used, and takes its name from the towns where it was developed.

• Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) • Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3.

A direct conversion of blast furnace slag to a mesoporous. In the iron manufacturing industry, it is unavoidable to produce large volumes of blast furnace slag (BFS) as a mineral residue from the preparation of pig iron in blast furnaces as well as to discharge a high volume of carbon dioxide (CO 2) gas as a result of the consumption of coke.These byproducts potentially …

The limestone is also decomposed to CaO that separates the silicate impurity of the ore in the form of Slag. It can be easily removed from the molten iron. Approximately 3-4% of Carbon and little quantities of many other impurities like sulphur, Silicon etc are contained in the iron manufactured in the Blast Furnace. The same is termed as Pig Iron.

SLAG IRON AND STEEL IBM The slag produced at blast furnace during pig iron manufacturing is called blast furnace slag The slag produced at steel melting shop is known as steel slag Slag output obtained during pig iron and steel production is variable and depends mainly on composition of raw materials and type of furnace Typically, for ore feed containing 60 to 65% …

Granulated blast furnace slag Just like air-cooled blast furnace slag, this slag has a hydraulic property and there is no risk of alkali-aggregate reaction. Because of the powerful latent hydraulic property that results from fine grinding, this slag is used in products such as Portland blast furnace slag cement.

In this zone Fe 2 O 3 is reduced to iron by co in three steps. 3Fe 2 O 3 + CO → 2Fe 3 O 4 + CO 2. Fe 3 O 4 + CO → 3FeO + CO 2. FeO + CO → Fe + CO 2. (Solid state) From the bottom of blast furnace, molten slag and molten iron are tapped out. This iron is impure and is called cast-iron or pig-iron. Go back to subject.

Slag binds the undesirable substances (gangue) and protects the liquid iron from excessive oxidation! About 20 % of the total tapped mass from the blast furnace is accounted for by the slag alone! Slag, however, is by no means a pure waste product but serves as a raw material for cement production.

12.5.2.2 Blast Furnace - The primary source of blast furnace emissions is the casting operation. Particulate emissions are generated when the molten iron and slag contact air above their surface. Casting emissions also are generated by drilling and plugging the taphole. The occasional use of an oxygen lance to open a

11.2.2 Ground-granulated furnace slag. Ground granulated blast-furnace slag, GGBFS, is a by-product of iron in blast-furnace. It mainly consists of silicate and aluminosilicate of melted calcium that periodically needed to be removed from the blast furnace. Similar to fly ash, the chemical compositions of GGBFS depend on the row materials used ...

Granulated Blast Furnace Slag. Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm (No. 4 sieve) in diameter to dense, sand-size grains passing a 4.75 mm (No. 4) sieve.

A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.

The slag obtained in the process of pig iron smelting has been widely used, but the variational hydration activity always is a significant factor affecting its quality. In this experiment, the laboratory simulated slag was prepared by adjusting the chemical composition and cooling method. The experi …

$470 million. Blast furnace slag was about 50% of the tonnage sold and accounted for 88% of the total value of slag, most of which was granulated. Steel slag produced from basic oxygen and electric arc furnaces accounted for the remainder of sales. Slag was processed by 28 companies servicing active iron and steel facilities or reprocessing old

The lower layer is of molten iron having some impurities while the upper layer is of molten slag. At the base of furnace a tapping hole is present from where molten iron is removed time to time. → The iron produced from blast furnace is known as Pig Iron. Pig iron has 4% carbon and many impurities in smaller amount (eg, S, P, Si, Mn).
