Graphite electrode is a kind of graphite conductive material with high temperature resistance. Graphite electrode is mainly made of oil-based or coal-based needle coke and coal tar pitch. The technological process of graphite electrode production includes mixing, molding, roasting, asphalt impregnation, re roasting, graphitization and machining. Graphite electrode can conduct current and generate electricity, so

1. Ash Ash increased after calcination. This is because the graphite rods emit a considerable amount of volatile matter during the calcination process, at the same time, there is a small amount of carbon oxidation, and ash in the calcination temperature can not be discharged, so the graphite rods in the forging when the more

Graphene exists in nature, but it is difficult to peel off the single-layer structure. Graphene layer by layer is graphite. Graphite with a thickness of 1mm contains about 3 million layers of graphene. When a pencil scratches gently on the paper, the trace may be several layers or even just one layer of graphene. In

The graphite electrodes produced in our country generally use straight-line joints, with less taper joints. The advantage of using cone joint is that it is easy to twist the joint, the joint hole is tapered so the hole wall of the joint hole is thicker, the strength of the hole wall at the impact is larger, the

In large-scale industrial production, it is difficult to reach the high temperature of 2000. However, in the process of high-temperature heat treatment and transformation, when the temperature reaches 2000 ℃, the thermal conductivity and conductivity of carbon change greatly. At this temperature, it has been able to achieve the good characteristics of graphite, with good

1.Problems of graphene dispersion Graphene has a single complete six membered ring structure, so there is a strong intermolecular force between graphene molecules, and the layers are easy to stack together, resulting in agglomeration. The surface of graphene is stable and inert, which makes it difficult to dissolve in basic solvents, and it is very
