When it comes to graphite electrodes, we are all familiar. Almost everyone has the experience of breaking up the dry battery when they are young, and then scribbling with the carbon rods inside. Although carbon rods are not strictly defined as graphite products, they do not contain much material. In fact, we can also imagine that the graphite electrode is the carbon rod in the enlarged dry cell, so we can know the shape of the graphite electrode. In fact, graphite products have many years of development history, since the early 1990s, after these years of continuous development, many products produced by our factory are widely used in mineral smelting, railway system and other high-tech industries.
Nowadays, more and more high-purity graphite rods are used. As a result, there are some problems in the use of graphite rods. For example, when the temperature reaches a certain condition, oxidation will occur. Next, we will put forward some solutions to this phenomenon. When the temperature of high-purity graphite rod reaches 400 ℃, it will turn red, which is the result of oxidation, but the oxidation speed is relatively slow at the beginning. In the process of temperature rising, the speed of oxidation is also faster and faster. Many people take the measure of adding nitrogen to reduce the speed of oxidation. In industrial production, the high temperature furnace is vacuumed to prevent the oxidation of oxygen in the air.
