Hollow Tubular High Silicon Cast Iron Anode Auxiliary Anode

[[MetaDescription]]

          Coke is mainly used in blast furnace iron making and blast furnace smelting of nonferrous metals such as copper, lead, zinc, titanium, antimony, mercury,etc Reducing agent, heating agent and column frame.Iron blast furnace using coke instead of charcoal, for the modern blast furnace scale Laid the foundation for the history of metallurgy.A major milestone in our history.In order to make the blast furnace operation to achieve better technical and economic Coke for smelting (metallurgical coke) must have appropriate chemical and physical properties, including during the smelting process Thermal properties.In addition to being widely used in iron making and non-ferrous metal smelting (metallurgical coke), coke is also used in casting, chemical industry, Calcium carbide and ferroalloy have different quality requirements.Such as casting coke, the general requirements of large particle size, low porosity, solid High carbon content and low sulfur content;The coke used in chemical gasification is not strict in strength, but it requires good reactivity and high ash melting point .The fixed carbon content should be increased as much as possible for carbide production coke.

• Product features：

1. Small specific gravity, loose texture, porous characteristics.
2. High carbon content, less volatile, stable physical and chemical properties.
3. With reference to foreign materials and product processing and manufacturing, and through strict screening, it has a fixed particle size composition suitable for the application of friction materials and plays an effective role.

• Application of products：

          Coke can be used to make graphite, smelting and chemical industry depending on its quality.The world's biggest user of petroleum coke is cement.Industry, which consumes about 40% of the market share of petroleum coke;Secondly, petroleum coke is calcined to produce aluminum Prebaked anode or graphite electrode for steelmaking, calcined with 22% petroleum coke.

1. Low sulfur, high quality cooked coke, such as needle coke, is mainly used for the manufacture of ultra-high power graphite electrode and some special carbon Product;Needle coke is an important material for developing new steelmaking technology in steel making industry.
2. Medium sulfur, common cooked coke, used in large quantities for aluminum smelting.
3. High-sulfur, ordinary coke, is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, and also as metal casting, etc The fuel used.
