What are the quality characteristics of graphite model

Graphite has a lot of different high -quality characteristics. It is widely used in the metallurgical industry forging, the setting glass of mezzanine, and the industrialization of semiconductor materials. What are the high -quality characteristics of graphite mold? Let's take a look with graphite products manufacturers.1. High -quality heat transfer and conductivity. The conductivity of graphite molds is 100 times higher than that of ordinary mining companies. The heat transfer is beyond metal composite materials such as steel, iron, and lead. The heat transfer coefficient decreases with the temperature, and even at a very high temperature, the graphite becomes anrmal insulation.2. Very good thermal resistance. The solution point of graphite is 385050 ° C, and the melting point is 4250 ° C. Even if it is burned by high temperature, high voltage and electricity, the net damage is not large, and the line expansion coefficient is not large.3. Excellent thermal shock -resistant character

Crystal structure

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. There is very little environmental pollution of metal materials: Because there is no bad matter that infiltrate the envi

The purpose of graphite machining

Various carbon graphite products, although they have a certain shape and size after forming, undergo expansion and contraction, deformation and bending, collision or corner dropping during the process of roasting, impregnation, and graphitization treatment from the pressed blank to the graphitized blank. The surface adheres to some fillers and insulation materials, resulting in roughness and unevenness. Their shape and size change to a certain extent, and they cannot achieve the shape of the product during use, Due to strict requirements for size and surface roughness, it cannot be used without mechanical processing. In addition, some products have complex structures and shapes that cannot be directly produced by forming methods, such as metal continuous casting and rolling graphite crystallizers, electric spark machining graphite molds, carbide sintering graphite boats, discs, and other special graphite products. Some products require interconnection when used, such as the connection

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.

What precautions should be taken when using graphite electrodes in electric furnace steel mills?

(1) Select the appropriate electrode variety and diameter based on the capacity of the electric furnace and the equipped transformer capacity.(2) During the loading, unloading, and storage of graphite electrodes, attention should be paid to preventing damage and moisture. The electrodes that are affected by moisture should be dried by the electric furnace before use. When lifting, the joint holes and surface threads of the electrodes should be protected.(3) When connecting the electrode, compressed air should be used to blow off the dust in the connector hole. The force used to screw the connector into the electrode connector hole should be stable and uniform, and the tightening torque should comply with regulations. When holding the electrode, it is necessary to avoid the joint area, that is, clamp it above or below the bottom of the electrode joint hole.(4) When loading furnace materials into the electric furnace, in order to reduce the impact of furnace material collapse on the ele
