Coke Metallurgy
Coke is one of the most important raw materials used in the iron production process using the blast furnace method. Coke is obtained by heating coal without the presence of air to a temperature higher than 1000 degrees Celsius and under a certain time; By performing this process, the volatile substances in the coal are removed as gas, and the black, porous and hard solid substance called coke remains. Coke is one of the most important and expensive raw materials used in the iron production process using the blast furnace method. Metallurgical coke is used as fuel and regenerating agent in steelmaking furnace
