The high grade anthracite should have a volitile of between 4-10% before being calcinated. Calcined anthracite is used as a carbon source in the manufacture of pre-bake electrodes, soderberg and tamping pastes, and carbon paste electrodes and blocks. Calcined antharcite is also an excellent smelting additive due to its high purity.

Calcined anthracite is raw anthracite that has been heat-treated. The process, known as calcination, takes place at high temperatures in electric or gas calcination furnaces. Gas-calcined anthracite is produced by annealing in a horizontal gas furnace at a temperature of around 1280 °C.

The global calcined anthracite market size was estimated at USD 3.16 billion in 2016. The market is anticipated to be driven by rising demand for carbon-rich charging materials in steel manufacturing. Low environmental impact and low product cost compared to calcined petcoke are expected to offer it a competitive edge over the next few years.

The raw anthracite is calcined in our own vertical shaft furnace. Each particle is calcined at a temperature of about 1200 °C which results in a very homogeneous end product. Therefore, the gas calcined anthracite retains its excellent grain stability and its good physical properties.

Calcined Anthracite Coal is made from anthracite under 1300 ℃ high temperature in calcined furnace.it has many grade from fix carbon 80%min to fix carbon 95%min .it is used in casting factory and related metallurgical industry.

Calcined Anthracite is raw anthracite that has beenheating treated. The process is known as calcination takes place at a high temperature in electric or gas calcination furnace. By heat treatment of anthracite coal will gain a more graphite-like structure. it is used to reduce impurities, graphitize the carbon, & physically stabilize the material.
