2023-10-25（1） Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, and coal tar pitch as a binder. They are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are conductors that release electrical energy in the form of an arc in an electric arc furnace to heat and melt the furnace material. According to their quality indicators, they can be divided into ordinary power, high power, and ultra-high power. Graphite electrodes include:(1) Ordinary power graphite electrode. Allowing the use of graphite electrodes with a current density below 17A/cm2, mainly used for ordinary power electric furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting.(2) Anti oxidation coated graphite electrode. A graphite electrode coated with an antioxidant protective layer on the surface forms a protective layer that is both conductive and resistant to high-temperature oxidation, reducing electrode consumption duri
2023-10-23Graphite bearings, due to their self-lubricating, high and low temperature resistance, corrosion resistance, and other characteristics, can meet the sealing requirements for strong corrosion, flammable, explosive, and radioactive media. Effectively solving the problems of "running, emitting, dripping, and leaking" in chemical equipment, it has a good effect on improving labor conditions, product quality, and productivity.Graphite bearings can be divided into rolling bearings and sliding bearings, and there are also different materials such as metal, non-metal, and composite materials. Graphite bearings are commonly used in sliding bearings, which are further divided into radial bearings and thrust bearings. The article mainly analyzes carbon graphite bearings, bronze graphite oil bearings, and embedded graphite bearings.The manufacturing method of graphite bearings is characterized in that it is achieved by the following technical solutions:1) . Model making: polystyrene foam plastic
2023-10-23Graphite crucible is a very excellent smelting tool that has been praised by people in the metal smelting industry. Its usage method is simple. Below, we will introduce some matters that need to be mastered when using it.The main uses of graphite crucibles include evaporation, concentration or crystallization of solutions, and burning of solid substances. It should be noted that although graphite crucibles have strong temperature adaptability and can be directly heated, they cannot be suddenly cooled after heating. If necessary, use crucible pliers to remove the crucible instead of using technical means to quickly cool it. Because it is directly heated and the heated contents are metals with extremely high dissolution temperatures, the required energy and safety requirements are relatively high. Therefore, during the heating process of the crucible, it is necessary to have a stable environment to ensure the safety and effectiveness of the operation. In general, manufacturers choose to
2023-10-20Spherical graphite is widely used due to its excellent conductivity, which is related to the use of graphite powder. Graphite products have been widely used in many domestic and foreign enterprises and have received widespread praise in the market. Graphite is widely used in the electrical and electronic industry as an electrode, positive electrode for rectifiers, graphite gasket, coating technology for telephone components, television picture tubes, and so on. Research on wear-resistant and lubricating system materials: Graphite is often used as a lubricant in mechanical development industrial enterprises. Graphite electrodes can be widely used in smelting and various alloy steel and iron alloys. At this time, our strong current can be introduced into the melting zone of the electric furnace through the working electrode.Spherical graphite has a wide range of applications in our daily lives regarding the use of graphite powder. What are its characteristics?1. High temperature resista
2023-10-19The price of spherical graphite is related to the use of graphite, which is widely used in many industrial fields.1. The price of spherical graphite is related to the use of graphite for refractory purposes, including bricks, crucible disasters, continuous casting powder, mold cores, molds, and refractory material detergents. Two important changes in the refractory industry are the widespread use of magnesium carbon bricks for steelmaking furnace lining and the application of aluminum carbon bricks in continuous casting. Graphite refractory materials, steel and other industries are closely related, and magnesium's MgO-C in the world has been widely used for steelmaking and has become a traditional use of graphite. Aluminum carbon bricks are mainly used for continuous casting of carbon refractory materials, and for flat protection of slabs such as pipelines and underwater nozzles. Molded refractory crucibles and related products produced from graphite crucibles and related products, su
2023-10-19What is the difference between graphite and diamond in the price of spherical graphite? Diamond, also known as diamond, feels like a sparkling scene, and its high price can only be deterred by most people. It is still a highly desirable diamond. Is there anything in diamonds? Its chemical composition is carbon C, and natural diamond is called pre polished post polished diamond "diamond". Natural diamonds are very small, with only two diamonds weighing more than 1000 carats in the world, and only a few diamonds weighing 400 carats. People hope to replace them with "artificial" diamonds, which is naturally associated with the "twin brothers" of diamonds - graphite.The chemical composition analysis of diamond and graphite is both carbon (C), known as "allotrope". This way of addressing is known to us because they have a certain amount of the same "quality", but their "shape" or "properties" are different and vastly dif
