Why are the quality indicators of high-power and ultra-high-power graphite electrodes superior to ordinary power graphite electrodes

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 low

What is the difference in the price of spherical graphite between graphite and diamond

What 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

The method of graphite formation of graphite mold

It is divided into two types of single -sided tablet computers and two types of tablets.1. Single -sided tablet computers continuously crushing methodThis type of rolling method can suppress soft graphite into board without all adhesives. The entire processing process is carried out on professional equipment with roller roller.The composition of the crushing mechanism: the material warehouse of the spider graphite 1, the vibration feeding equipment, 2, the delivery belt 3 four working pressure roller 4, a pair of electric heating device 5, the thick roller 6 pressure or pattern design roller 8 and roll roller 9 cutter 10 finished product roller rollerThe whole process of work: The high -purity graphite enters from the material warehouse to the feeding equipment and falls on the conveyor belt. After the rolling voltage of the work pressure roller, it produces a certain thin layer. The heating device causes high temperature to warm up, and the residual vapor body in the ingredients is o

What are the advantages of high-purity graphite?

The application fields of high-purity graphite include metallurgy, military, light industry, electrical battery industry, and fertilizer. Can it be called high-purity graphite? In order to make more people familiar with it, here are some related knowledge points about high-purity graphite for everyone? I hope you can bring some better help when choosing in the future.High purity graphite is widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, electronics, medicine, military industry, and aerospace. It has high purity and high strength graphite properties. In fact, the existence of graphite flakes now makes graphite have excellent lubricity. Generally speaking, the larger the ordinary graphite flakes, the better their lubricity. When we use it, we need everyone to know that the graphite industry technology is still at a relatively low level in the world, and the products are mainly raw materials and initial processing products. Therefore, th

Graphite products and other purposes

Defense industryIn the defense industry, the nozzle of solid fuel rockets is also used to make solid fuel rockets, the nasal cone of the missile, the parts of the universe navigation equipment, the insulation material and the anti -ray material.Anti -anti -rust and anti -rust materialGraphite can prevent boilers from scaling. Tests from relevant units show that adding a certain amount of graphite powder (about use per ton of water) to the water can prevent the surface of the boiler from scaling. In additionWith the continuous development of science and technology, people have also developed many new uses on graphite. Flexible graphite products. Flexible graphite, also known as expansion graphite, is a new graphite product developed in the age. The United States has studied successful flexible graphite sealing materials, solving the problem of atomic energy valve leakage, and then Germany, Japan, and France have also begun to develop and produce.

Analysis of the scope of application of industrial graphite in graphite products

Graphite products maintain the original chemical properties of flake graphite, namely acid resistance, corrosion resistance and physical properties, namely high temperature resistance 3000C and low temperature resistance 204C. Its compressive strength is greater than 800kg/cm2, and it is anti-oxidation. It loses weight in air at 450°C by 1 % , the rebound rate is 15-50% (density 1.1-1.5). It also has strong self-lubricating properties. Therefore, graphite products have been widely used in metallurgy, chemical industry, petrochemical industry, high energy physics, aerospace, electronics and so on.Using the characteristics of graphite, people have deftly made different types of products according to the needs of engineering: such as high-purity graphite products, flexible graphite products, composite graphite products and so on.

Graphite board antioxidant solution increases the period of use

After the formation of graphite board, it must be solved by antioxidantization. Generally, antioxidants are used, which is a thick liquid state. The ingredients are heat -resistant nano -ceramic particles. In the natural environment of air oxidation within 1300 ° C in the application temperature of the graphite board, its antioxidant actual effect is very good. After a variety of specifications of graphite boards with pre -immersed in the antioxidant protective film, its liquid can penetrate into the pores of the graphite board. The sexual protective membrane is exactly the reasonable blocking gas of this layer of protective membrane immediately touched with the graphite plate to produce oxidation reactions. Then it can reasonably resist the air oxidation of the graphite board and increase the use period of graphite board.The period of use of graphite boards has continued to increase, and the service life of traditional raw materials has already increased significantly.
