Graphite Rod Round Bar High Quality Vibration Carbon Industries 24-60 Gpa Requested 6-12 Ohm Ouzheng 1.62-1.90g/cm3 CN;SHN
Graphite rod
Graphite rod is most frequently used in the heating element of high temperature vacuum furnace, and the highest temperature of the graphite rod can reach 3000℃. It’s also widely used in a heat source or heat radiation of high-temperature environments and other various mechanical friction conditions. It has such traits as high thermal conductivity, high thermal stability, temperature shock resistance and excellent electronic property.
Significant Production Run
Raw material →Medium crushing →Milling →Screening →Dosing→Vibrated →Molding →Impregnation →Baking →Graphitization
NOTE: Our graphite block is made from the domestic high quality petroleum coke and needle coke, which is from China National Petroleum Corporation Daqing, Jinxi and Fushun petrochemical Company. So, we can guarantee the first-level quality.
