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.
blast furnace slag granulation Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product (granulated slag sand used as CO 2 -friendly substitute of clinker in cement production) rather than a difficult and costly waste material.
Ground granulated blast-furnace slag (GGBFS) is mainly consisting of CaO, SiO 2 and Al 2 O 3. In recent decades, the use of GGBFS as an alternative binding material (alkali-activated slag, AAS) and partial replacement of cement has increased, .
Synonyms: Slag cement, ground granulated blast furnace slag (GGBFS), granulated blast furnace slag (GBFS), Slag Product Form: Solid / powder or granular Intended Use of Product: Ground granulated blast furnace slag is used as an additive with portland cement in combination with water and aggregates to form concrete.
Blast furnace slag granulation at cast house. Blast Furnaces normally generate 250 to 350 Kg of liquid slag for every ton of hot metal produced. This molten slag is at around 1400 – 1550 deg C temperature. Till seventies blast furnace (BF) slag was considered a waste product and was being dumped at a convenient place away from the blast furnace.
Pelletized blast furnace slag, in contrast to air-cooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape. Grinding reduces the particle size to a cement fineness for use as a hydraulic cement, which is typically less than 3500 cm 2 /g. (8)
gravities of the steel slags stand out from the blast furnace slags which are closer to the specific gravities of natural aggregates. The dry and wet strengths of the steel slags are also much higher than the blast furnace slags.
Dry Granulation of Blast Furnace Slag for Energy Recovery Around 300 kg of liquid slag is produced as byproduct while producing one ton of hot metal in a blast furnace (BF).This slag is at a temperature of around 1500 deg C and has a sensible heat of approximately 400 M Cal per ton.
France. Air-cooled slag is being used as a substitute for stone. SiO2 and low Fe2 O3 can contribute to the formation of cement.1–0.5 0. C3 A-6-10. Utilization of blast furnace slag The blast furnace slag can be used in the preparation of materials such as ceramic glass. bricks. The crystalline phases of slag were identified as gehlenite.
Blast furnace slag (BFS, see Wikipedia ground granulated blast-furnace slag) is a nonmetallic byproduct of the manufacture of pig iron in a blast furnace. BFS consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates.
of iron, blast furnace slag is a renewable material, i.e. slag has not been previously used but has been formed as part of the iron making process. As slag leaves the blast furnace in a molten form at1500°C it is a homogeneous material free from foreign matter. TYPES OF BLAST FURNACE SLAG j Blast Furnace slag in Australia is produced in
wet cement, cement mixtures or liquids from wet cement. Burns should be treated promptly by a doctor. ... Blast Furnace Slag is a nonmetallic byproduct from the production of iron. The Silicon Dioxide may contain trace amounts of crystalline silica. Slag
XSD Sand Washer. The efficient sand washing machine of XSD series is a kind of cleaning equipment of international advanced level for sand and slag pellets, developed on the basis of introducing foreign outstanding technology of the same kind of products.
Granulated blast furnace slag (GBS) is a non-metallic by-product of the steel industry (annual GBS production is approx. 280 million tons) that is formed when after leaving the blast furnace the molten slag is quenched using powerful water jets or fast rotating drums in air.
NLMK Group is currently building a new briquetting plant at the Lipetsk plant. Briquettes will be manufactured from a mix of iron ore concentrate and blast furnace slag formed in the process of wet blast furnace gas cleaning. The plant will recycle more than 350,000t/yr of blast furnace waste.
Slag Dryer machine can dry the wet blast furnace slag with moisture content about 15% to be less than 1.5% as demand. Slag drying line mainly consists of the rotating cylinder, high-speed breakup equipment, lifting plate, self-cleaning device, gear transimission device, hot air furnace, reducer machine, supporting device, sealing device, air ...
The influence of ground granulated blast furnace slag (GGBFS) on the characteristics of fresh concrete will let us know more about the working of GGBFS in a broader way. This would develop the most future scope of GGBFS. Some of the main properties of fresh concrete by the incorporation of …
Wet granulation, slag pelletizing and dry slag atomization technologies were compared to better understand the flexibility that each process has to treat a range of blast furnace compositions and produce by-product slag suitable for sale.
