Answer
Description of Blast Furnace
The blast furnace is used to produce iron from iron ore, with the following raw materials:
- Iron Ore
- Coke: Acts as a fuel and reducer.
- Limestone: Acts as a flux to remove impurities.
Process Overview
- Charging: Iron ore, coke, and limestone are fed into the top of the furnace.
- Combustion: As the coke burns, carbon monoxide is generated, helping to reduce the iron ore.
- Slag Formation: Limestone combines with impurities to form slag that floats on top of the molten iron.
- Tapping: The molten iron is periodically tapped from the bottom, while slag is also periodically removed.
This process yields molten iron and slag, with the slag being a byproduct that can be utilized in various applications.
