Sintering has two reasons:
1- You want to put in the blast furnace an homogeneous mix of flux and mineral.
2- You want something with a lot of pores. So the reductor gas can make contact with a lot of surface.
A blast furnace is used to extract iron from its ore.
The raw materials typically used in a blast furnace include iron ore, coke, and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps to remove impurities during the smelting process.
blast furnace
its used a fuel , but has less calorific value as the carbon monoxide percentage is less which is the main combustible gas in the b.f gas. its used in heating the blast of hot air in the blast furnance itself and also can be used in rolling mill, sinter plant, and many more where you need heating
The three substances fed into the blast furnace are iron ore (in the form of sinter, pellets, or lumps), coke (a form of carbon derived from coal), and limestone (which helps remove impurities from the iron ore and acts as a flux).
The main products of a blast furnace are pig iron (used to make steel) and slag (a byproduct that is used in construction materials).
Blast furnace = Hochofen
Its because air is forced into the furnace to increase temperature. Steve.

Govăjdia Blast Furnace was created in 1810.
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.
