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 flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Method for manufacturing low-density expanded graphite blocks using flexible graphite

In recent years, various types of low-density carbon graphite materials have been actively studied, including carbon (graphite) foam made of mesophase pitch or polymer resin, and carbon nano foam formed when carbon materials are ablated by high repetition rate pulsed laser. Expanded graphite is also a low-density carbon graphite material. Due to the simple preparation process, low production cost, and convenience for large-scale industrial production of expanded graphite, research on expandable graphite has continued to deepen in recent years. The following editor from Jinhui Graphite Company introduced the method of making low-density expanded graphite blocks by soaking flexible graphite in concentrated acid:The worm like shape and weak macroscopic structure of expanded graphite limit its application. If a stable and expandable graphite block can be made, it will be beneficial for expanded graphite to play its role as a functional material for adsorption, insulation, thermal conducti

The difference between expanded graphite and ordinary graphene

Expanded graphite, also known as flexible graphite or vermicular graphite, is a new type of carbon material. Expanded graphite has many advantages, such as large specific surface area, high surface activity, good chemical stability, and high temperature resistance. The commonly used preparation process for expanded graphite is to use natural flake graphite as the material, which is first oxidized to form expandable graphite, and then expanded to form expanded graphite. Expanded graphite materials can instantly expand by 150-300 times in volume when exposed to high temperatures, changing from flaky to wormlike, resulting in a loose structure, porous and curved structure, expanded surface area, improved surface energy, and enhanced adsorption of flake graphite. Wormlike graphite can be self embedded between them, making the material have functions such as flame retardancy, sealing, and adsorption. It has wide applications in fields such as life, military, environmental protection, and c

Maintenance and upkeep of graphite crucibles

The graphite crucible must be strictly protected from moisture and must be stored in a dry place or on a wooden frame. When handling graphite crucibles, it is important to handle them with care and prevent them from falling or shaking. Before using them, they should be baked in a drying equipment or by the furnace to raise the temperature to 500 ℃. The graphite crucible should be placed below the surface of the furnace mouth to prevent wear and tear on the furnace cover. When adding materials, it should be based on the solubility of the crucible, and too much material should not be added to prevent tightening the crucible. The furnace outlet and crucible clamp should conform to the shape of the crucible, and the clamp in the middle should prevent damage to the crucible due to stress on the department. When removing slag and coke from the inner and outer walls of the crucible, it should be gently knocked to prevent damage to the crucible. A suitable distance should be maintained betwee

What are the advantages of high-purity graphite?

High purity graphite, also known as flake like high thermal conductivity carbon powder, is actually a product that we are talking about today. It also has characteristics such as high strength, oxidation resistance, high temperature resistance, good thermal shock resistance, small resistance coefficient, and easy precision machining. What are the advantages of high-purity graphite for everyone?High purity graphite is an ideal inorganic non-metallic material. High purity graphite has common advantages in the processing and manufacturing of structural casting molds, crucible pots for refining high purity metals, sintering molds, metal coating, and emission electron tubes. High purity graphite has corrosion resistance, with a uniform and fine matrix, which delays the corrosion degree of the product. In addition, it also has high thermal conductivity. The high content of fixed carbon ensures good thermal conductivity, shortens dissolution time, and significantly reduces energy consumption
