Manufacturing Process of High-Power Graphite Electrodes

The manufacturing process of high-power graphite electrodes involves several steps, including mixing, forming, baking, and graphitization. The first step is to mix the raw materials, which include graphite, pitch, and other additives. Then, a hydraulic press is used to form the mixture into green electrodes.

Next, the green electrodes are baked at high temperatures to remove any volatile materials and convert the pitch into a carbon binder. This process, known as carbonization, results in carbonized electrodes with low mechanical strength. The carbonized electrodes are then graphitized at even higher temperatures to increase their electrical conductivity and mechanical strength. The graphitization process can take several days and requires careful environmental control to prevent oxidation and other forms of damage to the electrodes.
