NINGXIA CARBONVALLEY INTERNATIONAL CO.,LTD(NORTHWEST INDUSTRY CO.,LTD)

         Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame. Blast furnace with coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy. For the blast furnace operation to achieve better technical and economic indexes of metallurgical coke (metallurgical coke) must have the appropriate chemical and physical properties, including the nature of the thermal state in the smelting process.
         Coke in addition to a large number of used in ironmaking and smelting non-ferrous metal (metallurgical coke), also used in casting, chemical industry, calcium carbide and ferroalloy, its quality requirement is different. If foundry coke, general demand big granularity, low porosity, high fixed carbon and sulfur content is low; Chemical gasification with coke, lax to strength requirement, but it requires good reactivity, high ash melting point; Calcium carbide production with focal requirements to improve the fixed carbon content as much as possible.
