What is Metallurgical Coke?

template_photo_1Metallurgical coke is made from low ash, low sulfur bituminous coal, with special coking properties, which is inserted into ovens and heated to 1200 Deg to fuse fixed carbon and inherent ash and drive off most of the volatile matter. The final product is a nearly pure carbon source with sizes ranging from foundry coke (coke breeze).

Processing

Metallurgical_Coke_Market_Outlook_-_309x194Metallurgical coal is used in the production and purification of metallurgical coke. It is during the heating process that the unstable components are released. The final product is a non-melting, solid, stable carbon. However, the “ash” elements, which were part of the original bituminous coal, remain encapsulated in the resultant met coke. One attribute of met coke is its ability to burn while producing little or no smoke. Narayani Coke obtains high quality metallurgical coke from Australia, China, Colombia, The United States, and various European countries.

End Uses

Met coke is used in products where a high quality, tough, resilient carbon is required. Met coke, limestone, and iron ore are mixed together in high temperature furnaces where extreme heat causes the chemical properties to bond, forming iron and steel. More than 95 percent of the met coke produced is used in the iron and steel industries.
