    Blast furnace slag is a nonmetallic coproduct produced in the process in the production of iron from iron ore or iron scrap. It consists primarily of silicates aluminosilicates and calcium-alumina-silicates. The molten slag which absorbs much of the sulfur from the charge comprises about 20 percent by

    Slag Ground granulated blast furnace slag (GGBS) GGBS is primarily a latent hydraulic binder used as a type 2 addition to cement which produces Portland blastfurnace cement (6-35 of GGBS) or blastfurnace cement (36-90 GGBS) which is produced primarily by blending at the concrete mixer but can also be used to produce factory blends generally at the cement factory.

    The blast furnace operates on the counter-current principle with the supply of iron ore and coke from the top into the blast furnace and the oxygen-enriched hot air required for the coke combustion process blown from below via tuyeres. In the furnace combustion melting and reduction zones are formed from bottom to top. The iron ore is reduced to pig iron in the reduction zone which is

    Unlike air-cooled and expanded blast furnace slag pelletized blast furnace slag has a smooth texture and rounded shape. Consequently the porosity and water absorption are much lower than those of ACBFS or expanded blast furnace slag. Pellet sizes range from 13 mm (1/2 in) to 0.1 mm (No. 140 sieve size) with the bulk of the product in the minus 9.5 mm (3/8 in) to plus 1.0 mm (No. 18 sieve

    Using Cooled Mirror Hygrometers to optimize Cold Hot Blast Furnace processes Application Background The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron. The blast furnace is a huge steel stack lined with brick. Iron ore coke and limestone are dumped into the top and preheated "hot blast" air is blown into the bottom. The raw
