TECHNICAL SPECIFICATION
Coking coal, also known as metallurgical coal, is a type of coal used in the production of steel. It is a key ingredient in the steelmaking process, as it provides the carbon necessary for the production of coke, which is used to reduce iron ore to pure iron.
Characteristics
Steam coal typically has:
1. High carbon content: Necessary for the production of coke.
2. Low ash content: Affects the quality of the coke produced.
3. Low sulfur content: Affects the quality of the steel produced.
4. Good coking properties: Necessary for the production of high-quality coke.
Uses
Steam coal is primarily used for:
1. Steel production: Used in the production of coke, which is used to reduce iron ore to pure iron.
2. Iron production: Used in the production of pig iron.
3. Other industrial applications: Used in the production of ferroalloys, electrodes, and other products.
Types of Coal
Common types of steam coal include:
1. Hard coking coal: Used in the production of high-quality coke.
2. Semi-soft coking coal: Used in the production of lower-quality coke.
3. Weak coking coal: Used in the production of low-quality coke.
Production and Trade
Coking coal is produced and traded globally, with major producers including:
1. Australia: Largest exporter of coking coal.
2. United States: Major producer and exporter of coking coal.
3. Canada: Major producer and exporter of coking coal.
4. India: Major consumer of coking coal.
