Metallurgical coal or coking coal [1] is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. [2] [3] [4] The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that ...
Raw coke. Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges.
The price of metallurgical coal is volatile [112] and much higher than the price of thermal coal because metallurgical coal must be lower in sulfur and requires more cleaning. [113] Coal futures contracts provide coal producers and the electric power industry an important tool for hedging and risk management .
Coking coal (metallurgical coal or "met coal") is used in the manufacture of steel. A good coking coal must have excellent agglomeration properties, a high carbon content, and a low content of sulfur, phosphorus, and ash. The best unblended coking coal is high quality medium-volatile bituminous coal. [18]
Arch Coal (NYS: ACI) engages in the production and sale of thermal coal for use in electric utilities and metallurgical coal for the steel industry. Today, let's look at three things investors ...
Coking is the process of heating coal in the absence of oxygen to a temperature above 600 °C (1,112 °F) to drive off the volatile components of the raw coal, leaving behind a hard, strong, porous material with a high carbon content called coke. Coke is predominantly carbon.
Metallurgical coal miners Walter Industries and Alpha Natural Resources are trading at prices not seen in 10 years. There is blood in the streets as the sector contends with oversupply caused by ...
HG and UHG anthracite are used as a coke or coal substitute in various metallurgical coal applications (sintering, PCI, direct BF charge, pelletizing). It plays an important role in cost reduction in the steel making process and is also used in production of ferroalloys , silicomanganese, calcium carbide and silicon carbide .
