Graphite electrode is a kind of electrode commonly used in chemical industry, metallurgy and other industries. It is a conductive material made of high-purity graphite. Its excellent conductivity makes it maintain stable electrical performance under some high temperature and high pressure conditions.
The production of graphite electrode requires certain technological processes and standards. Next, we will introduce the standard production process of graphite electrode in detail.
The main raw material of graphite electrode is graphite. The purity and quality of graphite have an important influence on the performance of graphite electrode. Generally, the purity of graphite is required to be above 99.9%, and the infrared spectrum should meet the standard requirements.
The first step in preparing graphite is to separate natural graphite minerals by chemical methods. The separated graphite needs to go through multiple fine preparation processes, including ball milling, oscillation, ultrasonic dispersion and other processing processes, so that its purity and quality have been further improved.
The refined graphite powder is processed into graphite rod raw material by means of discharge heating or high-frequency induction heating. In this process, the raw material needs to be cut and adjusted to ensure that the size and shape of the graphite rod meet the requirements.
Next, the molding process is carried out. The graphite rod is pressed into the shape and size required by the mold, and the graphite electrode element is formed after molding. After forming, the original graphite electrode should be machined and surface treated, and at the same time, it should be baked at high temperature for many times to optimize the physical and chemical properties of the graphite electrode.
Finally, impurity analysis and quality inspection are carried out for graphite electrode to determine whether its overall quality meets the requirements of relevant standards. The qualified graphite electrode will be re-inspected to ensure its stable quality and meet the requirements of industry standards.
In short, the above is the standard manufacturing process of graphite electrode. A high-quality graphite electrode with stable quality can only be achieved through a number of tedious processes, and any error in one of them will affect the overall performance and service life of the graphite electrode. Therefore, the graphite electrode manufacturer needs to attach great importance to the quality control of the graphite electrode in all aspects, ensure the excellent quality of the graphite electrode produced and improve the practical value of the product.
