The primary use of coking coal is in the production of coke. Coke is created by heating coking coal in the absence of air to high temperatures (up to 2000°C or 3632°F) in specialized coke ovens. This process, known as carbonization, drives off volatile matter and transforms coal into coke. The resulting coke is a porous, carbon-rich material ...
test of coking properties, the Gray-King coke type. The Gray-King coking test measures the agglutinating properties of coal when carbonized under prescribed conditions, i.e. it is a measure of the power of coal to form a coherent coke. The different Gray-King coke types are shown in Fig. 2. (The ECE 376
A coking plant is used to produce coke (coking coal) from metallurgical coal. Coking plants consist of coke ovens (aka coking ovens, coke furnaces, coking furnaces). Coal is used to reduced iron ore to produce pig iron (aka hot metal) in the blast furnace (BF).However, it cannot be burned directly in the furnace because it contains numerous …
Coke is the pyrolyzed and annealed product of coking coal which plays a vital part in the BF ironmaking process. As a hard and porous material, coke acts as structural support media against the weight of the ferrous burden materials charged to the BF and provides pathways that facilitate gas and liquid transport through the BF.
coking coal globally, two for PCI coal, one for semi-soft coking coal and four for metallurgical coke, for locations of loading/ delivery detailed in the table below. Platts also assesses 17 individual brand relativities daily on a CFR China basis and 11 on FOB Australia basis, as well as a range of metallurgical coal
Coking. Coking coal is an essential raw material for the production of iron and steel. Coke is a solid carbonaceous residue formed from coking coal (a low-ash, …
Hard coking coal is used in the coke ovens. It is a necessary input in the production of strong coke. The semi-soft coking coal (also known as medium/weak coking coal) is used in the coal blends along with hard coking coal. Coal for PCI is used for its heat value and injected directly into the blast furnace as a replacement for coke.
The assessment is based on a standard specification of prime-quality low-volatile hard coking coal with 71% coke strength after reaction and 21.5% volatile matter, among other standard specifications. Coking coal was priced annually until 2010, when quarterly pricing became the most common method.
To make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process. First, it provides the heat needed to melt the ore, and second, when it is burnt, it has the effect of 'stealing' the oxygen from the iron ore, leaving only the pure iron behind. In the coking plant, coal is heated in the absence of oxygen to 1250c.
Metallurgical coke is produced from coking coals in a coking process, which is basically the carbonization of coal at a temperature of about 1000–1100 °C in the absence of air. Production of coke takes some 18–20 h to assure that the charge is completely carbonized ( Dıez et al., 2002 ).

Conditions for sustained high coking coal prices. Prices for coking coal, as with other commodities, have experienced extreme increases in the past. The Queensland floods in 2010 and 2011 removed a significant portion of seaborne supply and resulted in prices that pushed past $350 per metric ton Free on Board in Australia.
The second batch of 30,000 tons of coking coal was also completed and collected at the port simultaneously. It will arrive and be delivered in December as planned, and then the third and fourth batches will be formed…operated on a regular basis according to demand, exporting coking coal from China to Indonesia has become an important …
Coking coal and thermal coal are two types of coal that are used for different purposes. Coking coal, also known as metallurgical coal, is primarily used in the production of steel. It has high carbon content and low impurities, making it ideal for the manufacturing of coke, which is a key component in the steelmaking process.
The coking industry is an important basic energy and raw material industry, which connects coal, coke and steel industries and plays an important role in the industrial chain, economic construction, social development and so on [1,2].With the development of large-scale blast furnaces, the requirements for coke quality have gradually improved, …
Coking coal is the type of coal which on heating in the absence of air undergoes a transformation into a plastic state, swells, and then solidifies to form coke. Coking coals …
The coking process includes coal preparation, coal charging, coke pushing, coking, coke quenching, coke storage screening, byproduct recovery, water treatment and other processes, showing the characteristics of complicated engineering, emission points and abundant pollution (Pilarczyk et al., 2013). The BTH region is one of the regions …

Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas, …
In reactive coke production studies, these by-products were added to the coking coal blend at certain rates, and coking processes were carried out. …

The Coal AF is petroleum coke; therefore, it has no rheological and conventional petrographic properties due to its inherent characteristics. However, the CCP value of petroleum coke was also determined with similar methodologies of coking and non-coking coal. Petroleum coke has the least coking potential, which is 1.20 [1].

Coke Making Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. Coking coal must also have low sulphur and phosphorous contents.
