  B. product introduction;

Sanneng Carbon Co., Ltd., graphite electrode (factory one) produces12in UHPgraphite electrode  , Used in EAF and LF for steel making, as well as in electric smelting furnace for producing industrial silicon, phosphorus, etc

After calcined needle coke and petroleum coke are crushed, ground, sieved and mixed with additives according to the proportions in Table 1. After dry mixing in a 5L kneading pot for 40 minutes, add coal pitch and hot mix for 40 minutes (the pitch temperature is 180  , The amount of addition is based on experience, based on the fact that the paste is advantageous for compression molding), the mixing temperature is 170 , and then the Φ75 mm mold is used for hot compression molding at 120  under a pressure of 32MPa. The green body was immersed and fired twice and graphitized at 2600  to obtain a sample of graphite electrode.
