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

Types and uses of carbon solid raw materials

Carbon graphite material is a granular structure material made from various raw materials with different particle sizes, through the addition of binders, kneading, forming, roasting, and graphitization. Therefore, the performance of materials is not only related to the particle size, type and dosage of binders, as well as process control and operation during the production process, but also to the type and performance of the raw materials themselves.There are many solid raw materials used in the production of carbon graphite materials, such as ordinary petroleum coke, needle shaped petroleum coke, asphalt coke, artificial graphite, natural graphite, carbon black, anthracite, metallurgical coke, charcoal, sugar charcoal, bone charcoal, and so on; For electrochar products, there are also metal powders such as copper, silver, tin, lead, and artificial resins; For mechanical carbon and furnace lining materials, as well as silicon carbide, carbon dioxide, and patterned clay; For carbon fib

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.

Graphite material properties

Graphite materials are mainly composed of polycrystalline graphite and belong to inorganic non-metallic materials. However, they are called semi metals due to their excellent thermal and electrical conductivity. Graphite has higher thermal and electrical conductivity than certain metals, and also has a much lower coefficient of thermal expansion, high melting point, and chemical stability than metals. This makes it of great value in engineering applications. Graphite has good corrosion resistance and does not react with any organic compoundsGraphite is another high-temperature resistant material that does not melt at high temperatures. It also has good thermal shock resistance and excellent self-lubricating propertiesThe disadvantage of graphite is its poor seismic performance. It begins to oxidize at 500 ℃ in the atmosphere, and the oxidation rate increases with the increase of temperature
