Ironworks
· Charging. After the ground ores have been processed in forms of sinter and pellets (see article iron ore mining and dressing), they are stored in bunkers in the iron works and mixed with lump ore as this mixture is then fed to the blast furnace together with coke as fuel, additives are added (also called fluxes).These mixture is referred to as charge.

Why is iron produced in a blast furnace converted to steel?
· Well, in a blast furnace, Iron ore (iron oxide) is converted into Iron. That molten iron is converted into steel in a basic oxygen furnace in a subsequent process. So iron is not converted into steel in the blast furnace. Chemical reactants and flux materials to chemically reduce iron oxide to iron.

Iron
The pig iron produced by the blast furnace process contains up to 4–5% carbon (by mass), with small amounts of other impurities like sulfur, magnesium, phosphorus, and manganese. This high level of carbon makes it relatively weak and brittle.

What's the Process of Iron Smelting?
· The main products of blast furnace smelting are pig iron and ferroalloy, and the byproducts are slag, gas and furnace dust. pig iron. Pig iron is an iron carbon alloy with more than 2% carbon, which also contains Si, Mn, s, P and other impurities. Pig iron can be divided into two egories according to its use and composition.

Pig Iron
· The molten iron thus produced is known as pig iron. The slag from the blast furnace consists of calcium, aluminium and ferrous silies. It is used as a blast for railroads, mixed with tar for Road making and in cement manufacturing. The pig iron from the blast furnace contains 90 to 92 % of iron.

So, the correct answer is Pig iron Option C. Note: To further reduce the carbon content of pig iron, the obtained metal is melted again with some coke and iron flakes in a blast furnace. This formed iron is known as Cast Iron and has a little less level of carbon which is [2 3% ] as compared to the pig iron and is much harder in nature than the pig iron.

What Are the Uses of Blast Furnace Slag ...
· When pig iron is smelted in a blast furnace, the flux is added to the raw materials from the blast furnace in addition to iron ore and fuel (coke). When the furnace temperature reaches ℃, the lime in the flux reacts with the aluminate, silie and coke ash in the ore at high temperature and chemically combines to form a nonmetal product called blast .

Pigiron production with charcoal in blast furnaces requires approximately the same amount as coke, tons per ton. This corresponds to about 2 tons of dry wood per ton of iron. In view of the fact that pig iron production generally is conducted in comparatively large units, it follows that forestry operations to supply charcoal for blast furnaces must normally be of a size .
