Graphite is widely used in the electrical industry for electrodes, brushes, carbon rods, carbon pipes, mercury tubes, cashiers, cashmerers, telephone parts, televisions, coatings of televisions, and so on. Among them, the application of graphite electrodes is the most widely used. When smelting various alloy steel and iron alloy, use graphite electrodes. At this time, the powerful current passes through the melting area of the electric furnace to generate an arc, which translates the electric energy to the heat energy, and the temperature is increased to the left and right. So as to achieve the purpose of melting or reaction. In addition, when electrolytic metal magnesium, aluminum, and sodium, the anode of the electrolytic groove also uses graphite electrodes. The resistance furnace that produces rigid sand was also used as a furnace head conductive material with graphite electrode. The graphite used in the electrical industry is high in granularity and taste. For example, alkaline batteries and some special electric carbon products are required to control the grain size of the graphite within the range, quality or above, and the harmful impurities (mainly metal iron) are required below. Graphite used in the TV of the TV, the granularity requirements are below. Graphite for wear -resistant and lubricating materials is often used as lubricants in the mechanical industry. Lubricating oil is often not used under high-speed, high temperature, and high pressure conditions, and graphite wear-resistant materials can work without lubricating oil at a temperature at a high sliding speed. Many devices that transport the corrosive media are widely used to make piston rings, sealing rings and bearings. When they operate, they do not need to add lubricant. Graphite is also a good lubricant when many metal processing (drawing and pulling tube).
2023-12-11Raw material quality: The main raw material for graphite crucibles is natural graphite, and its quality is closely related to the service life of graphite crucibles. High quality natural graphite has the characteristics of high density, high purity, and high strength, which can extend the service life of graphite crucibles.
The current density of graphite electrodes used in high-power and ultra-high-power electric furnaces significantly increases, resulting in the following problems: (1) due to resistance heat and hot airflow, the temperature of the electrodes increases, resulting in an increase in the thermal expansion of the electrodes and joints, and an increase in the oxidation consumption of the electrodes; (2) The temperature difference between the center of the electrode and the outer circle of the electrode increases, and the thermal stress caused by the temperature difference also increases accordingly. The electrode is prone to cracking and surface peeling; (3) After the power of the electric furnace is increased, the electromagnetic force increases, causing severe vibration and increasing the probability of electrode breakage.Therefore, the physical and chemical properties of high-power and ultra-high-power graphite electrodes must be superior to ordinary power graphite electrodes, such as low2023-08-15Why are the quality indicators of high-power and ultra-high-power graphite electrodes superior to ordinary power graphite electrodes
