Coking coal and pulverized coal consumed in making steel.
Coal of any grade useful in steel-making... more on: Metallurgical coal
Coal, typically bituminous, which is heated in a substoichometric atmosphere to the extent that the volatile matter of the coal is released and the coal passes through the "plastic stage" to become metallurgical coke, which is used as the carbon input in an integrated steel mill.
Coal that meets the requirements for making coke. It must be low in ash and sulfur and form a coke that is capable of supporting the charge of iron ore and limestone in a blast furnace.
Various grades of coal suitable for carbonization to make coke for steel manufacture. Also known as "met" coal, it possesses four important qualities: volatility, which affects coke yield; the level of impurities, which affects coke quality; composition, which affects coke strength; and basic characteristics, which affect coke oven safety. Met coal has a particularly high Btu, but low ash content.
coal suitable for steel production
" means the various grades of coal suitable for making steel, such as coking coal, which is used to make coke, and PCI coal, which is used in the steelmaking process for its calorific value."
Various grades of coal suitable for steelmaking. These include coking coal, used to make coke, and non-coking coal, which is pulverized and injected into a blast furnace as a heat source in steelmaking
Coal of high quality used to produce coke. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Synonym: coking coal.
