It acts as a Heat insulator. It prevents escape of heat, thus keeping the iron in molten state.
It also prevents fire inside the furnace.

Does iron ore slag sink to the bottom of the blast furnace?
Slag is the waste which is skimmed off the top of the molten iron that comes out of the blast furnace. It is a mixture of calcium and magnesium compounds, plus other impurities such as iron oxide, but is mainly calcium silicate. The formula for calcium silicate is CaSiO3.
What are The components of a slag heap?
If your refering to what is left over from a blast furnace then the main component would be calcium silicate left over from the coke.
How calcium oxide is formed in a blast furnace?
Calcium oxide is not formed here, it is added.
What goes into a blast furnace?
Sinter, which is a mixture of iron ore, coke and limestone, and a blast of hot air. Externally to the furnace, iron ore, coke and limestone are mixed together Intimate mixing ensures that the reactants are as close as possible to each other. This is loaded into the top of the blast furnace. A blast of hot air ( ~ 1100 oC) is sent in at the bottom of the furnace, through tuyeres. The oxygen (air) is also one of the reactants. The products are tapped from the bottom of the furb=nace are liquid iron and 'slag' ( calcium silicate).
What is the German word for blast furnace?
Blast furnace = Hochofen
What raw materials are used in a blast furnace?
Iron ore or Haematite (Fe3O2), Carbon in the form of 'Coke', and Limestone (Calcium Carbonate 'CaCO3') are all used in the blast furnace. Iron Ore is melted down with coke, the coke burns heat into the furnace. Oxygen gas is blasted in from the sides. The carbon (C) and oxygen (O2) react to form carbon dioxide gas (CO2). At higher temperatures more carbon (C) is reacted with the carbon dioxide(CO2) to create carbon monoxide (2CO). The carbon monoxide 'steals' the oxygen from the iron oxide (Fe3O2), reducing the iron oxide to iron. Due to the impurities in the iron, it is called 'pig iron'. Limestone (CaCO3) is added to remove the impurities from the iron. The limestone (CaCO3) reacts with mainly silicate in the iron, and becomes calcium silicate (CaSiO3) and carbon dioxide (CO2). Calcium silicate is known as 'slag' and is used for construction.
What is Blast Furnace?
A blast furnace is used to extract iron from its ore.
Why blast furnace called as blast furnace?
Its because air is forced into the furnace to increase temperature. Steve.
When was Govăjdia Blast Furnace created?
Govăjdia Blast Furnace was created in 1810.
What Is A Blast Furnace?
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.

How does limestone coke and iron ore get into the blast furnace?
through the top of the blast furnace
