Recently, India has started a safeguard probe into sudden and sharp increase in the imports of metallurgical coke.
About Metallurgical Coke:
- It is a carbonaceous material produced by heating bituminous coal in the absence of air.
- It is produced by heating coal in coke ovens at high temperatures (around 1,000 to 1,200 degrees Celsius).
- It is used as a fuel and reducing agent in the production of iron and steel.
- It has an open, porous structure and may appear glassy in some varieties.
- It has also a low volatile content or rather low waste product content due to the heat treatment process received.
- It has a high carbon content, low ash content, and high strength.
- Its porous structure allows for good gas flow and provides structural support in the blast furnace.
- However, the “ash” constituents, that were part of the original bituminous coal feedstock, remain intact in the finished product.
- Met Coke is available in a wide range of sizes; from fine powder (30 mm) to basketball-sized lumps (20 cm).
Q1) What is Bituminous coal?
Bituminous coal is a type of coal that falls in the middle of the coal rank spectrum in terms of carbon content and energy value. It is a dense, black or dark-brown coal that is widely used as a fuel for electricity generation, industrial processes, and heating.
