Graphite physicss

The chemical properties of single -mass carbon at room temperature are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; burning with oxygen at different high temperatures to generate carbon dioxide or carbon dioxide; Below, single -quality carbon is more likely to be oxidized by acid; at high temperature, carbon can also react with many metals to generate metal carbides. Carbon is restored and can smell metal at high temperature.Graphite is soft, black and gray; it is greasy and can contaminate paper. The hardness is 1-2, and the hardness can be increased to 3 to 5 along the vertical direction. The proportion is 1.9 ～ 2.3. The surface area is concentrated at 1-20m2/g.

How to turn a graphite block into a carbon increase agent

How to turn graphite blocks into carbon increases Gentle blocks are indispensable in the production process of carbon and graphite products in the production process of carbon and graphite products. Equipment external forces to get rid of the adhesion between the molecular structure of the raw material and break the raw materials. Since then, everyone can divide them into rough, shattered, sophisticated, fine grinding, etc., but they can divide them according to the broken and boring size and their particles. The same industrial production has a broken specification for different industrial production.Today, as far as everyone is concerned, the three crushing levels in the production of graphite products can be divided into pre -fragmentation, medium crushing and fine grinding. The crushing in front of the burning furnace is generally broken up to 50-70mm on the large graphite block of 200mm. The medium crushing means that the particle size is broken after forging.

The main production process of graphite electrodes

(1) Calcination. Both petroleum coke and asphalt coke need to be calcined at a temperature of 1350 ℃ to fully remove the volatile matter contained in the carbonaceous raw material and improve the true density, mechanical strength, and conductivity of the coke.(2) Crushing, screening, and batching. Crush and screen the calcined carbon raw materials into designated size aggregate particles, grind some coke into fine powder, weigh according to the formula, and aggregate to form a dry mixture of various particles.(3) Mix and knead. Mix and knead the dry mixture of various particles with a certain amount of binder in a heating state to form a plastic paste.(4) Forming. Under external pressure (extrusion molding) or high-frequency vibration (vibration molding), the paste is pressed into a certain shape and high density of raw electrodes.(5) Roasting. Place the raw electrode in a specially designed roasting furnace, and use metallurgical coke powder to fill and cover the raw electrode. At a

The Price of Spherical Graphite and Its Use

The 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.

The main methods of graphite purification

1 Flotation methodFlotation method is a commonly used method for purifying minerals. Due to the difficulty of water infiltration on the surface of graphite, it has good floatability and is easy to separate from impurity minerals. In China, flotation method is generally used for beneficiation of graphite.The flotation of graphite raw ore generally uses the positive flotation method first, followed by reverse flotation of the positive flotation concentrate. High grade graphite concentrate can be obtained by using flotation method. The grade of flotation graphite concentrate can usually reach 80% to 90%, and the purity can reach around 98% by using multi-stage grinding.The commonly used collectors for flotation of crystalline graphite are kerosene, diesel, heavy oil, sulfonic acid esters, sulfate esters, phenols, and carboxylic acid esters. The commonly used foaming agents are 2 # oil, 4 # oil, terpineol oil, ether alcohol, and butyl ether oil. The adjusting agents are lime and sodium ca

How to distinguish the advantages and disadvantages of graphite

The first aspect is the flexural strength of the material. The flexural strength of a material is a direct reflection of its strength, indicating the tightness of its internal structure. Materials with high strength have relatively good resistance to loss during discharge. For electrodes with high precision requirements, it is recommended to choose materials with better strength.The second aspect is the Shaw hardness of materials. In the subconscious understanding of graphite, it is generally considered a relatively soft material. But actual test data and application situations show that the hardness of graphite is higher than that of metal materials. In the special graphite industry, the commonly used hardness inspection standard is the Shore hardness measurement methodThe third aspect is the average particle diameter of the material. The smaller the average particle size of the material, the more uniform the discharge of the material, the more stable the discharge condition, and the
