Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces. Heat and pressure cause physical and chemical changes that result in carbon-rich coal.
Metallurgical coal differs from thermal coal, used for energy and heating, by its carbon content and its caking ability. Caking refers to the coal39s ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coalgenerally classified as a metallurgical gradeis harder and blacker. It contains more carbon and less moisture and ash than low-rank coals.
The grade of coal and its caking ability is determined by the coal39s ranka measure of volatile matter and degree of metamorphismas well as mineral impurities and the ability of the coal to melt, swell and resolidify when heated. The three main categories of metallurgical coal are.
Hard coking coals like anthracite have better coking properties than semi-soft coking coals, allowing them to garner a higher price. Australian HCC is regarded as the industry benchmark.
While PCI coal is not often classified as coking coal, it still isused as a source of energy in the steelmaking process and can partially replace coke in some blast furnaces.
Coke making is effectively the carbonization of coal at high temperatures. Production normally takes place in a coke battery located near an integrated steel mill. In the battery, coke ovens are stacked in rows. Coal is loaded into the ovens and heated in the absence of oxygen up to temperatures around 1,100 degrees Celsius 2,000 degrees Fahrenheit.
Without oxygen, the coal does not burn. Instead,it begins to melt. The high temperatures volatilize unwanted impurities, such as hydrogen, oxygen, nitrogen, and sulfur. These off-gasses can either be collected and recovered as by-products or burned off as a source of heat.

Properties inherent in the initial input coal heavily influence the ultimate quality of the coke produced. A lack of a reliable supply of individual coal grades means that coke-makers today often use blends of up to 20different coals to offer steelmakers a consistent product.
Approximately 1.5 metric tonsof metallurgical coal are required to produce one metric ton 1,000 kilograms of coke.
