Which raw materials are selected for the production of traditional carbon materials

Various metallurgical furnace carbon blocks (such as blast furnace carbon blocks, ferroalloy furnace carbon blocks, calcium carbide furnace carbon blocks, and aluminum electrolysis cell cathode carbon blocks, etc.) are used at a certain high temperature. Therefore, carbon blocks should have high mechanical strength, thermal stability, and corrosion resistance, but the ash content requirements are not too strict. Except for the bottom carbon blocks used in aluminum electrolysis cells, it is not necessary to measure conductivity. The production of carbon blocks mostly uses anthracite as the aggregate and metallurgical coke as the filling material. To improve the thermal conductivity and corrosion resistance of carbon blocks, a certain amount of graphite fragments (or natural graphite) can be added. In order to improve the thermal conductivity and conductivity of carbon blocks, semi graphite carbon blocks can be produced by electrocalcining anthracite.The raw materials used for conductiv

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

Introduction to the characteristics of flake graphite

1. As a basic raw material, flake graphite can be processed into ultrafine graphite powder, expanded graphite, nano graphite powder, high-purity graphite powder, etc.2. Flake graphite has good lubricity, high temperature resistance, conductivity, etc. Processed into solid graphite lubricant, widely used in mechanical lubrication.3. The quality of flake graphite depends on its carbon content. By purifying flake graphite, it can be processed into high carbon, medium carbon, and low carbon flake graphite. Each type of graphite has a different carbon content, and the higher the carbon content, the better its industrial use.Flake graphite has strong thermal shock resistance and good corrosion resistance, making it the main carbon material for carbon refractory materials. It has important factors affecting the corrosion resistance and high-temperature working strength of carbon refractory design materials such as magnesia carbon bricks. In the actual production process, carbon refractory ma

Material characteristics of graphite powder

Graphite powder is a substance that is very sensitive to chemical reactions. In different environments, its resistivity will change, which means its resistance value will change. However, there is one thing that does not change. Graphite powder is one of the good non-metallic conductive substances. As long as the graphite powder is kept uninterrupted in an insulated object, it will also be electrified like a thin wire. However, there is no accurate number for the resistance value, Because the thickness of graphite powder varies, the resistance value of graphite powder will also vary when used in different materials and environments. Due to its special structure, graphite has the following special properties:1) High temperature resistant type: The melting point of graphite is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with te

Prevention and gray removal of graphite production and processing workshop

The anti -pollution -proof of graphite production and processing workshop is stable in the physical properties of ash graphite and no organic chemical corrosion. Therefore, the removal of the ash in the workshop does not need to consider anti -virus and corrosion resistance, mainly to reduce the concentration value of smoke and dust in the air and collect tiny smoke.First, to ensure the sealing of graphite production and processing workshop, and prevent environmental pollution from smoke and dust. Graphite production and processing workshop air has graphite smoke dust. Graphite smoke should be collected and purified according to the dust removal equipment before removing the workshop.In the secondary, graphite production and processing should be based on the concentration value of the smoke and dust caused by the system. Different CNC lathes, different concentrations of production and processing processes are different. For example, the concentration value of the smoke and dust concen

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

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.

Graphite mold mold polishing

The mold polishing of graphite mold is accompanied by the common use of plastic products, such as daily chemical tools and drink packaging materials. The appearance must usually specify the surface of the injection molding mold concave mold to be polished. The production of optical lenses, laser laser records and other molds are extremely high in surface roughness, so the provisions of polishing and polishing are also very high. Following and polishing not only enhances the beautiful and generosity of product workpieces, but also improves the corrosion resistance and abrasion resistance of the surface of the raw material, but also enables the mold to have other advantages, so that plastic products are easy to produce and reduce the time of production and manufacturing injection processing cycle. Therefore, polishing and polishing is an important process in the process of injection molding.The mold polishing has two meters; one is to increase the smoothness of the mold, so that the sur
