Ground granulated blast furnace slag (GGBS) is a nonmetallic product obtained as a byproduct from the blast furnaces used to make iron. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. The size of its particles is less than 45 microns and specific surface area is about 400 to 600 m 2 /kg.
#0183;#32;Blastfurnace slag, which is the byproduct generated by quenching molten iron slag, is suitable for recycling. The global production of steel slag in 2014 has been estimated to be 247 million
Granulator or rock slag when cooled in pits Excess Hot gases flow from top of Furnace to Gas Cleaning Plant and reused for heating Layers of Coke amp; Ferrous materials descend over 8 hrs to bottom of furnace soften then melt Carbon Refractory Lining Cast Iron / Copper Stave Cooling system
There are two methods in which slag can be fed to any slag granulation plant. The first involves a granulator which is located close to the furnace and enables the slag to be delivered to the plant direct from the slag runner. The second is a system 288 ISSN
The slag runner that feeds the pilot plant at voestalpine Stl in Linz, Austria. The final product: dry slag sand with a glass content of 9497% can serve as a premiumquality substitute for cement clinker. A look into the dry slag granulator: Slag enters from above, hits a rotating cup at the center and is atomized.
Liquid slag produced in a blast furnace (BF)is at a temperature of around 1500?C and has a sensible heat of around 400Mcal/ton. BF slag is rich in CaO, SiO2, Al2O3, and MgO which are similar to the components of Portland cement. When this liquid BF slag is cooled fast enough then the solidified slag has a large percentage of glassy phase with high cementations activity and hence it can be used
Each year, approx. 400 million tons of blast furnace slag is produced worldwide with a tapping temperature of around 1,500#176;C. Currently, the slag is granulated in wet granulation plants using large volumes of water and to date it has not been possible to utilize the remnant heat energy of the molten slag, with approx. GJ of energy per ton.
Slag granulation using water sprays is now an established technology that not only simplifies blast furnace casting floor operations but also provides an economical route for producing of a valuable raw material for a host of industries. The slag granulation plant comprises three sections: for granulation, dewatering and storage.
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 2friendly substitute of clinker in cement production) rather than a difficult and costly waste Wurth has developed the INBA #174; slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
