This metals recovery operation (using magnetic separator on conveyor and/or crane electromagnet) is important to the steelmaker as the metals can then be reused within the steel plant as blast furnace feed material for the production of iron. Additional information on steel slag aggregate use in the United States can be obtained from:
Ground Granulated Blast Furnace Slag (GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. It is suitable for applications in marine environment, mass concreting and sulphate environment, water retaining structures, basement and ...
Properties and Uses of Iron and Steel Slag MF 1826 NATIONAL SLAG ASSOCIATION Page 5 Granulated blastfurnace slag is produced by quickly quenching (chilling) molten slag to produce a glassy, granular product. The most common process is quenching with water, but air or a combination of air and water may be used.
Ground granulated blast furnace slag (GGBS) is a byproduct from the blastfurnaces used to make iron. These operate at a temperature of about 1, 500 degrees centigrade and are fed with a carefully controlled mixture of ironore, coke and limestone.
INMAA INTERNATIONAL has also been a prime supplier for the EAF (electric arc furnace) slag and Blast Furnace Slag which manly use in Cement manufacturing, eminent exporter of Carbon Black Powder, Steel Powder and various kind of refractory Bricks. We have been supplying and exporting in Saudi Arabia as well as all across the world and has been ...
Dec 18, 2015· Groundgranulated blastfurnace slag is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a ...
slag powder and blast furnace slag so the recycling of steel slag can bring enormous benefits and environmental benefit to whole society.[9] 6. Ground granulated blast furnace slag is commonly used in combination with Portland cement in concrete for many applications[10,11] 7. The heat of hydration is dependent on the Portland
The ground granulated slag powder is drying by the hot air supplied by hot blast furnace, and with the help of hot air, the powder selecting is made in the separator. The qualified slag powder particles will be collected by bag dust collector, then conveyed to and stored in the silos by the air slide and elevator.
offers 5,051 slag powder products. About 5% of these are refractory, 1% are slag, and 1% are iron scrap. A wide variety of slag powder options are available to you, such as free samples, paid samples. There are 4,945 slag powder suppliers, mainly located in Asia.
The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a coproduct of steelmaking, and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route.
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Ground granulated blastfurnace slag (GGBFS) or Slag Cement is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. GGBFS is used to make durable concrete structures in
The ground granulated blast furnace slag (GGBFS) is a byproduct of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree ...
In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed.
Historically, the resmelting of iron ore slag was common practice, as improved smelting techniques permitted greater iron yields—in some cases exceeding that which was originally achieved. During the early 20th century, iron ore slag was also ground to a powder and used to make agate glass, also known as slag glass.
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a nonmetallic product called blast furnace slag.
AirCooled Blast Furnace Slag. Crushed ACBFS is angular, roughly cubical, and has textures ranging from rough, vesicular (porous) surfaces to glassy (smooth) surfaces with conchoidal fractures. There can, however, be considerable variability in the physical properties of blast furnace slag, depending on the iron production process.
Aug 04, 2011· The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into .
Ground granulated blast furnace slag is produced by pulverizing granulated blast furnace slag produced by blast furnaces as a byproduct of the ironmaking process. This hydraulic admixture is popular for use as raw material for Portland blast furnace slag cement, admixture for raw concrete, and other applications.
Ground granulated blastfurnace slag (GGBFS) or Slag Cement is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. GGBFS is used to make durable concrete structures in
* The majority of components in Granulated Blast Furnace Slag are various glassy Metallic Silicates (Iron, Calcium, Magnesium, Aluminum, and Titanium Silicates), including: Dicalcium Silicate (Ca 2 SiO 4 ), Merwinite (Ca 3 MgSi 2 O 8 ), and Gehlenite (Ca 2 Al 2 SiO 7 ) .
Blast Furnace Slag Fine Aggregate Blast Furnace Slag Coarse Aggregate. Does not contain chloride, organic impurities, clay, shells, and other similar material. Eliminates the potential for alkali aggregate reactions. Road construction material: Iron and Steel Slag for Road Construction. The hydraulicity of this material makes roadbeds more durable.
Converter slag In the same way as aircooled blast furnace slag, converter slag is cooled slowly by natural cooling and water spray in a cooling yard. It is then processed and used for various iron and steel slag (converter) applications. Approximately 110 kg of slag is generated for each ton of converter steel. Electric arc furnace slag
From a materials requirements perspective, a blast furnace refractory lining may be split into five areas from top to bottom. Upper shaft: In this low temperature area, abrasion by the solid burden is the primary mode of wear. Our SiC 85P, a silicate bonded SiC, has proven to be a costeffective solution.
