Needle coke is a key raw material for producing high-power or ultra-high power graphite electrodes
Needle coke is a high-quality coke with a clear fibrous texture, a particularly low coefficient of thermal expansion, and easy graphitization. When the coke block ruptures, it can split into thin and elongated particles (usually with an aspect ratio of 1.75 or above) according to the texture. The...Read more -
Ingredients and design for producing graphite electrodes
In the production process of various graphite electrodes and graphite products, ingredient is a very important process. The design and operation of ingredients have a significant impact on the quality of finished products and the yield of finished products in processes such as molding, roasting, ...Read more -
Precautions for using graphite electrodes
(1) Wet graphite electrodes should be dried before use. Remove the foam plastic protective cap from the spare electrode hole and check whether the internal thread of the electrode hole is complete. (2) Clean the surface and internal threads of the spare graphite electrode with compressed air that...Read more -
Requirements for particle size of raw materials for producing graphite electrodes and graphite products
The particle size composition of aggregates refers to the proportion of particles of different sizes. Mixing particles of different levels in a certain proportion instead of using only one type of particle is to make graphite electrode products have higher density, smaller porosity, and sufficie...Read more -
Production of graphite electrode roasting process
Baking is one of the heat treatment processes in the industrial production of graphite electrodes and graphite products. The roasting of formed raw products is carried out indirectly in the roasting furnace using materials such as coke powder (or quartz sand) as protective media, under the condit...Read more -
Selection of Carbon Raw Materials for Graphite Products
Carbon raw materials include: natural graphite, recycled graphite, graphite electrodes, medium to coarse particle graphite, high-purity graphite, isostatic pressure graphite, graphite derivative products and other graphite product raw materials. The carbon raw materials used in different industri...Read more
