Properties and Uses of Iron and Steel Slag MF 182-6 NATIONAL SLAG ASSOCIATION Page 5 Granulated blast-furnace 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.

Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes.

Ground granulated blast-furnace slag (GGBFS) or Slag Cement is obtained by quenching molten iron slag (a by-product of iron and steel-making) 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 slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route.

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 .

Dec 18, 2015· Ground-granulated blast-furnace 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 ...

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:

slag powder and blast furnace slag so the recycling of steel slag can bring enormous benefits and environ-mental 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

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

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.

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 cost-effective solution.

Alibaba 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 ground granulated blast furnace slag (GGBFS) is a by-product 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 ...

Ground granulated blast furnace slag is produced by pulverizing granulated blast furnace slag produced by blast furnaces as a by-product of the iron-making process. This hydraulic admixture is popular for use as raw material for Portland blast furnace slag cement, admixture for raw concrete, and other applications.

Blast furnace slag is used in the production of cement (iron Portland and blast furnace cement). Air-cooled blast furnace slag is formed by allowing the molten slag to cool relatively slowly under ambient conditions; final cooling can be accelerated with a water spray.

Historically, the re-smelting 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.

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

Converter slag In the same way as air-cooled 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

Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.

Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. These operate at a temperature of about 1, 500 degrees centigrade and are fed with a carefully controlled mixture of iron-ore, coke and limestone.

Air-Cooled 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.

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.

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 ...

Ground Granulated Blast Furnace Slag (GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) 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 ...
