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 coal's ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coal—generally classified as a metallurgical grade—is 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 coal's rank—a measure of volatile matter and degree of metamorphism—as 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:
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 20 different coals to offer steelmakers a consistent product.
After the blast furnace is fed with these materials, hot air is blown into the mixture. The air causes the coke to burn, raising temperatures to 1,700 degrees Celsius, which oxidizes impurities. The process reduces the carbon content by 90% and results in a molten iron known as hot metal.
The hot metal is then drained from the blast furnace and sent to the BOF, where scrap steel and limestone are added to make new steel. Other elements, such as molybdenum, chromium, or vanadium, can be added to produce different steel grades.
Production efficiency in the blast furnace process is highly dependent upon the quality of raw materials used. A blast furnace fed with high-quality coke will require less coke and flux. The use of high-quality product actually lowers production costs and results in a better hot metal.
In 2013, an estimated 1.2 billion metric tons of coal were used by the steel industry. China is the world's largest producer and consumer of coking coal, accounting for about 527 million metric tons in 2013. Australia and the United States follow, producing 158 million and 78 million metric tons, respectively.
