(PDF) Slag granulation systems for blast furnaces

Slags formed in blast furnaces contaminate environment. However, granulation of the slags makes it possible to produce valuable building material. Utilization of the granulated slag in cement...Blast Furnace Slag Granulation at the Cast House – IspatGuru,Blast Furnace Slag Granulation at the Cast House A blast furnace (BF) is a closed system into which iron-bearing materials (iron ore lump, sinter and/or pellets), fluxes (slag formers) and reducing agents (i.e. coke) are continuously fed from the top of the furnace shaft through a charging system.Granulated Blast Furnace Slag - an overview,,Granulated blast furnace slag should contain calcium oxide (CaO), magnesium oxide (MgO), and silicon dioxide (SiO 2), the sum of which should account for at least two-thirds of the mass. The remaining third contains aluminium oxide (Al 2 O 3), with small amounts of other compounds.

Ground granulated blast-furnace slag - Wikipedia

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. Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing compound which improves the strength, durability and appearance of the concrete. IBMD - Granulated Blast Furnace Slag Manufacturer in India,Granulation process is the controlled quenching of the slag in cold water which does not give time for crystalline growth to take place. During this process of quenching, the molten slag undergoes accelerated cooling under controlled water flow condition and gets converted into glassy sand with 97 % of the solid granulated slag particles less than 3 mm and an averageBlast Furnace Slag - an overview | ScienceDirect Topics,Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled. Depending on the cooling method the BFS can be produced as air-cooled, granulated, expanded and
