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.
Properties
- 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).
