Calcined Anthracite Coal (CAC)
Calcined Anthracite Coal (CAC) Description
Calcined anthracite coal is a form of anthracite coal that has been subjected to high-temperature processing, typically in a rotary kiln or a vertical furnace, to remove volatile components and increase its carbon content. This process makes the coal more suitable for various specialized applications due to its enhanced properties.

Application
Steel Production
Calcined anthracite is used as a carbon additive in the production of steel. It serves as a recarburizer, providing carbon content to the molten iron during the steelmaking process.
Ferrous Foundries
It is employed in foundry applications to improve the carbon content of the melt and control the composition of cast iron.
Aluminum Smelting
In some cases, calcined anthracite can be used as a carbon additive in the production of aluminum, similar to its application in steelmaking.
