Carbon materials (petroleum coke, needle coke, and coal tar pitch) are calcined at high temperature, and then pressed, roasted, impregnated and graphitized to make carbon graphite electrodes.
Carbon-graphite electrode definition
Graphite electrode is a product obtained by graphitization of carbon material. In an electric arc furnace, at a high temperature above 2300°C, amorphous carbon will finally be converted into graphite which has a three-dimensional ordered planar hexagonal grid layered structure. Graphitization furnaces mainly have two kinds. One is Acheson graphitization furnace, the other is Length-wide graphitization furnace (LWG) .
Carbon graphite electrode cost
Each ton of finished graphite electrodes require 1.02 ton of raw materials and 0.29 ton of binder. The cost of raw materials accounts for 66.88%.
The power cost in production processes such as roasting, graphitization, and machining accounted for 16.77%.
Labor costs in manufacturing processes accounted for 8.02%.
Manufacturing costs accounted for 8.33%.
RP, HP, UHP graphite electrode production cost calculation formula:
CPC -- Unit price per ton of petroleum coke
CNC --Unit price per ton of needle coke
CC -- Unit price per ton of coal tar pitch
Carbon graphite electrode manufacturers
Nowadays, the graphite electrode industry is highly competitive. So, a large number of manufacturers compete the market of RP 300 GE (or lower grades) through fighting price war. Those bad behaviors result a bad phenomenon that the quality of graphite electrodes degrade sharply. For enterprises in steel industry, they put their priority on seeking well-known graphite electrode manufacturers and high-quality products. They hope to purchase outstanding graphite electrodes with a great price!
