Who many stage in Blast furnace

Question

Accepted Answer

There are three main stages in a blast furnace: preheating, reduction, and refining.

Preheating stage involves heating the furnace and charging it with raw materials like iron ore, coke, and limestone.
Reduction stage involves the conversion of iron ore into molten iron by removing oxygen through a chemical reaction with carbon monoxide.
Refining stage involves further processing the molten iron to remove impurities and adjust the composition to desired levels.
Each stage is crucial for the efficient operation of the blast furnace and the production of high-quality iron.
Examples of blast furnaces include those used in steelmaking and iron production.
