Blast Furnace Slag For Pelletisation Of Iron Ore Europe
Granulated Blastfurnace Slag - Euroslag
1500 °C. Molten iron and slag are drawn off at regular intervals from tap holes at the base of the furnace. The quenching of this liquid slag with an excess of water (granulation), air and water (pelletisation) or steam forms a granular product. For each ton iron about 1.6 tons raw material, 330 kg coke, 150 kg coke coal powder and

Blast furnace metallurgy Britannica
In Europe, the blast furnace developed gradually over the centuries from small furnaces operated by the Romans, in which charcoal was used for reducing ore to a semisolid mass of iron containing a relatively small amount of carbon and slag. The iron mass was then hammered to remove the slag, yielding wrought iron.

Slag recycling - recovery
The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron.

Blast furnace - Wikipedia
Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and ...

Iron and Steel Slag Market Size, Share, Industry Forecast 2028
Iron and steel slag, also referred to as ferrous slag, are created by adding calcareous (or dolomite), silica sand , and lime to blast furnaces to remove contaminants from iron ore, and other ferrous feed resources and to reduce the heat conditions of iron and steel processing. Iron and steel slag is a by-product in the method of steelmaking.
