Product Description

High Conductivity Carbon Graphite Electrodes with Nipples​

 

Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials and coal pitch as a binding agent. They are made through calcination, batching, kneading, pressing, roasting, graphitization and machining. They release electric energy in the form of arc in an electric arc furnace. Conductors that heat and melt the charge can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes according to their quality indicators.
 
Features ​1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will specially design the production procedure, so as to ensure the reliability of product quality. 2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible. 3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out. 4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite crucible. 5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time of dissolution, and remarkably reduce the energy consumption.
