The key features of graphite

1. High fever and conduction: In response to the use of raw materials such as graphite with high thermal conductivity, it reduces the time of fusion.2. High temperature resistance: high -temperature resistance has strong impact characteristics, for rapid cold and hot heat, not easy to crack.3. High temperature resistance: high fire resistance, high temperature to 1200 to 1600 ° C.4. Anti -corrosion resistance: strong adhesion to resist melting soup.5. Anti -reflective impact: have a certain anti -reflective impact resistance (when the funds of the melt material are invested, etc.).6. Antioxidant: Graphite is very easy to oxidize at high temperatures in oxidation. Due to the development of oxidation solution, oxidation consumption is less.7. Anti -adhesion: Because graphite is not easy to stick to the soup, the molten soup is soaked and attached with less adhesion.8.

Which raw materials are selected for the production of graphite electrodes

(1) Raw materials for the production of artificial graphite electrodes. All low ash raw materials such as petroleum coke and asphalt coke can be used to produce high-quality graphite electrodes. Adding asphalt coke is to improve the strength of the product. The production of ordinary power graphite electrodes can use ordinary quality petroleum coke as raw material; Produce high-power graphite electrodes using high-quality petroleum coke and some needle coke; To produce ultra-high power graphite electrodes, high-quality needle coke must be used as the raw material. To produce high-purity graphite electrodes, petroleum coke with very low ash content is required. In order to improve the lubricity and plasticity of the paste and improve the conductivity of the product, a portion of graphite chips is also added to the production ingredient of graphite electrodes.(2) Raw materials for the production of natural graphite electrodes.

Pure method of high -carbon graphite

The flotation method is a type of energy consumption and reagent consumption and low cost in the conventional purification method of minerals. This is the advantage of the floating method purification method. For scales -shaped graphite, multi -segment mills cannot be completely unbuttoned, but they are not conducive to protecting large scales of graphite. Therefore, the use of flotal methods to further improve the graphite taste. High carbon graphite containing more than 99%of carbon must use chemical methods to use graphite.(1) Pure method of alkaline acid. The carbon content after the purity method of alkaline acid method can reach more than 99%, which has the characteristics of less one -time investment, high product quality, and strong process adaptability. The purity of metal mines can adopt the advantages of alkaline acid method). The alkaline acid method is a wide range of methods in my country today; its disadvantages are large energy consumption, long response time, large gr

The main impregnating agents currently used for graphite

(1) Carbon based materials: Most carbon based materials use asphalt, but in order to control the filling rate, tar or asphalt is often mixed with low carbonization rate and low viscosity carbon based materials such as tar and creosote. They are carbonized through heat treatment after impregnation, so the residual material entering the pores is only carbon. The carbon process is currently a standard carbon process aimed at improving density, strength, conductivity, thermal conductivity, corrosion resistance, and wear resistance. It has become the most common treatment method for general carbon materials, especially in the production process of fine structured graphite and UHP electrodes for electric furnace steelmaking. It is an indispensable process. In order to achieve the same goal, there are also cases of impregnating synthetic resin and then roasting and carbonization. The carbonization of synthetic resin generally generates hard carbon, which is characterized by greatly increasin

The Function and Conditions of Adhesive

Carbon graphite material is a powder structure material similar to refractory materials and concrete. Except for non-ferrous brushes and mechanical metal graphite products, which are formed as a whole with a certain strength by phase transformation of metal powder at sintering temperature, the powder particles of typical carbon graphite materials cannot spontaneously bond together even at high temperatures. In order for them to bond into a whole with a certain shape and strength, a certain amount of substance that can bond carbon powder particles or fibrous fine substances into a whole must be added, and this substance is called a binder.The conditions that the adhesive should meet:1) The adhesive should be able to mix with the main material to form a plastic substance.2) The binder becomes a viscous liquid within an appropriate temperature range. And it can have good adhesion and adsorption with the particles of the main material, and has a large adsorption force.3) The binder should

The use of scales graphite and colloid graphite

Scales graphite is a very widely used non -metallic powder product, with good thermal conductivity, conductivity and lubrication effect; colloid graphite is a graphite product that uses natural scales graphite as the main raw material.
