Graphite electrode, mainly petroleum coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading,molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, with low resistivity, good conductivity, low ash, uniform and compact structure, good oxidation resistance, high mechanical strength, etc.
The advantages of our products
* High density, high temperature resistance, high mechanical strength and strong chemical stability.
Graphite electrode is a kind of high temperature resistant conductive material, widely used in many fields. Its main applications include:
1. Electric furnace steelmaking. Graphite electrodes are used to make steel in electric furnaces by introducing a current into the furnace and using the heat generated by the arc discharge for smelting. Depending on the capacity of the furnace, graphite electrodes of different diameters are used and connected by threaded joints to achieve continuous use.
Electric ore furnace .
2. Graphite electrode is also used in mineral thermal furnace, which is mainly used for the production of ferroalloy, pure silicon, yellow phosphorus, matte and calcium carbide. In these processes, the lower part of the conductive electrode is buried in the charge and heat is generated by electric arcs and charge resistance.
Resistance furnace.
3. Graphite electrodes are also used in various resistance furnaces, such as graphitization furnaces for producing graphite products, melting glass furnaces and electric furnaces for producing silicon carbide.
4. Processing into special-shaped products. A large number of graphite electrode blanks are processed into crucibles, graphite boats, hot die casting molds and vacuum electric furnace heating bodies and other shaped products, in the quartz glass industry, graphite electrodes are also used in the production of electric melting tubes and quartz bricks.
5. Aluminum electrolysis. Graphite electrodes are also used in aluminum electrolytic cells to conduct electrical energy and generate an appropriate arc during electrolysis.
6. In addition, the graphite electrode has other applications, such as the synthesis of graphite materials at high temperatures, graphite molds and graphite crucible, etc. These applications mainly involve the conductivity and corrosion resistance at high temperatures. According to different use environments and needs, there are different types of graphite electrodes, such as ordinary power graphite electrode, high power graphite electrode, ultra-high power graphite electrode and oxidation resistant coating graphite electrode.
