Electrically calcined Anthracite, unlike ordinary carbon bricks, is manufactured by calcining anthracite at up to 2000 degC in a calciner. The anthracite undergoes partial graphitization and low volatile matter during the process. This material of excellent quality has outstanding thermal stability and refractoriness. It can be used as an alternative to metallurgical coke in ladle and blast furnaces for production of prebake electrodes, Soderberg and tamping pastes and cathode carbon blocks.
The recarburizer is used in the production of anodes in aluminum smelting, and also in the basic oxygen steelmaking process. This is a more efficient alternative to petroleum coke. Castings are also of higher quality. Additionally, the low sulfur content and volatile matter helps to reduce the amount of additives used in furnaces.
The market for Electrically Calcined Anthracite for high-performance refractories is expected to grow significantly in the coming years. This market is expected to grow in the coming years due to the increase in steel and metal product demand, coupled with the focus being placed on water filtration. This global market can also be classified by type of product, geographical region and application. On the basis of application, there are three main categories: Pulverized coal injection (PCI), basic oxide steelmaking and electric arc kilns. PCI dominates the market, with a significant share.
There are many companies that operate in the Electrically Calcined Anthracite Market. Shanxi Hongqiqu New Material Co. Ltd. Rheinfelden Carbon GMBH Ningxia Hengtai Carbons Co. Ltd. Zhengzhou Xinhua Raw Materials Technology Co. Ltd. They are implementing innovative strategies in order to increase their product ranges and market share.
With the increasing demand for electricity vehicles, the market of calcined coal will also grow quickly. A surge in energy consumption due to industrialization, urbanization, and other factors will drive the demand for calcined alumina. In addition, the global calcined anthracite market is expected to be driven by the emergence of renewable energy sources, which will further increase the demand for carbon products in the near future.
Calcined anthracite is a high-carbon fuel that has excellent thermal stability, refractoriness, chemical and electrical conductivity. This fuel is used by steel and aluminum companies for many different applications. Calcined anthracite is also low in ash, moisture, and toxic gases.
The global calcined anthracite industry is divided into gas calcined anthracite and electrically calcined anthracite. Electrically calcined anthracite offers more benefits than gas calcined anthracite, such as a lower volatile matter content and a higher graphitization level. Moreover, electrically calcined anthracite can be made into carbon bricks without the need for refractory additives. This makes it an economical alternative to conventional carbon bricks, which require expensive refractory additives. Moreover, electrically calcined coal has a lower sulfur and volatile matter content than normal anthracite coal. This helps in avoiding the expansion of anthracite in the smelting process, which results in a higher carbon yield.
