08-05 2019What is high-purity graphite
- High purity graphite refers to a type of graphite with higher purity. There are many types of graphite raw materials, which can be divided into isostatic pressed graphite, molded graphite, and extruded graphite according to the molding method during the production period. Molded graphite is high-purity graphite, which is molded using a 10000 ton hydraulic press and then baked for several months before being made into finished products. Therefore, high-purity graphite has high purity and good physical properties, and is widely used in various industries, making it a high-quality raw material for industrial production. High purity graphite refers to graphite with a carbon content greater than 99.99%, widely used in the metallurgical industry, advanced refractory coatings, military pyrotechnic material stabilizers, pencil leads for light industry, carbon brushes for the electronics industry, electrodes for the battery industry, catalyst additives for the fertilizer industry, etc.

08-05 2019What are the characteristics of graphite products
- 1、 Graphite products have excellent adsorption properties.The open space structure of charcoal gives it excellent adsorption properties, so charcoal is often used as an adsorption material to adsorb moisture, odors, toxic substances, etc. The graphite product manufacturer has conducted experiments and found that the graphite baking tray used for grilling meat a few days ago looks very clean, but when heated on an induction cooker, the oil and harmful substances adsorbed during the last grilling will gradually seep out. However, there is no need to worry, just wipe it clean with clean meal paper and it can be used.2、 Graphite products have excellent thermal conductivity, fast heat transfer, uniform heating, and fuel savings.Baking pans and pots made of graphite heat quickly and evenly, cooking food from the inside out in a short heating time. Not only does it have a pure taste, but it also locks in the original nutrients of the food. We have conducted experiments where when grillin...

08-05 2019Application of graphite electrode
- (1) Ordinary power graphite electrodes allow the use of graphite electrodes with current densities below 17A/cm2, mainly used in ordinary power electric furnaces for steelmaking, silicon refining, yellow phosphorus refining, etc.(2) Anti oxidation coated graphite electrodeA graphite electrode coated with an antioxidant protective layer (graphite electrode antioxidant) on the surface. Forming a protective layer that is both conductive and resistant to high temperature oxidation, reducing electrode consumption during steelmaking (19%~50%), extending electrode lifespan (22%~60%), and reducing electrode energy consumption. The promotion and use of this technology can bring about such economic and social effects:① Graphite electrodes consume less per unit, resulting in a certain reduction in production costs. For example, in a certain steel plant, based on the consumption of approximately 35 graphite electrodes per week for the first level LF refining furnace and 165 refining furnaces w...

08-05 2019A Brief History and Varieties of Graphite Electrodes
- Graphite electrode is a high-temperature resistant graphite conductive material made by using petroleum coke and asphalt coke as particle materials, coal tar pitch as binder, and undergoing processes such as kneading, forming, roasting, graphitization, and mechanical processing. Graphite electrode is an important high-temperature conductive material for electric furnace steelmaking. Electric energy is input to the electric furnace through graphite electrode, and the high temperature generated by the arc between the electrode end and the furnace charge is used as a heat source to melt the furnace charge for steelmaking. Other electric smelting or electrolysis equipment also often uses graphite electrode as a conductive material. In 2000, the world consumed around 1 million tons of graphite electrodes, while China consumed around 250000 tons of graphite electrodes. The excellent physical and chemical properties of graphite electrodes have been widely used in other industrial sectors, an...

The expansion process of graphite electrode
- The internal battery's vapor is a key reason for the bulging of the battery. Whether the battery is in a normal cycle system, temperature cycle system, and maintained at high temperatures will cause different levels of vapor expansion. Graphite electrodes are made from petroleum coke and needle coke as raw materials, asphalt binder as a melting agent, and processed through forging, seasoning, mixing, pressing, sintering, graphitization, and mechanical processing. They are electrical conductors that release electromagnetic energy in an electric arc in a medium frequency furnace to heat and melt waste materials. According to their quality standards, they can be divided into general output power, high power, and extremely high output power. The key components of graphite electrodes include four types: general output power graphite electrodes, oxidation resistant coated graphite electrodes, high-power graphite electrodes, and extremely high output power graphite electrodes. Graphite...

08-05 2019What aspects should graphite products be maintained in
- The main uses of graphite are widespread, including insulation bricks, pliers pots, continuous forging powder, casting cores, molds, cleaning agents, and corrosion-resistant materials. Because graphite products have many high-quality properties, they are widely used in industries such as metallurgy, mechanical equipment, electrical equipment, chemical plants, textiles, and national defense and security.When maintaining graphite products, it is necessary to ensure the following aspects:1. Prevent strong erosion flames from directly spraying graphite products on the side and bottom of the engine;During the entire application process, the turning point of graphite products should be adjusted once a week to increase their service life;3. Applying appropriate combustion aids and preservatives will reduce the service life of graphite products;4. A moderate distance should be maintained between graphite products and the furnace wall, and graphite products should be placed in the center of th...
