The formation of KISH graphite

Whether it plays an important role in the growth of KISH graphite or the growth of KISH graphite according to layer -like crystal, oxygen is an important role. Practice has proved that when the co -crystal iron fluid is exposed to the air, the KISH graphite is easy to form; turning the iron solution and the update surface can exacerbate the precipitation of KISH graphite. The action of oxygen is to form SiO2 as the base of KISH graphite nucleus. The temperature of the iron liquid temperature at below 1400 ° C is severe than high temperature because of SiO2, which is unstable above 1400 ° C. The precision phenomenon of KISH graphite cannot be seen in the low Si or Si iron liquid, which shows that the existence of SIO2 has an impact on the formation of KISH graphite that cannot be ignored.The cooling speed is the basic process conditions formed by the formation of KISH graphite when the existence of oxygen (such as hydrogen protection). KISH graphite can only be formed at a lower coolin

How are graphite electrodes consumed in electric furnace steelmaking?

The consumption of graphite electrodes is mainly related to the quality of the electrodes themselves, as well as to steelmaking operations and processes.(1) Electrode end consumption. Its consumption includes the sublimation of graphite material caused by high arc temperature, as well as the loss of chemical reactions between the electrode end and molten steel and slag. The electrode end consumption is also related to whether the electrode is inserted into the molten steel to increase.(2) Oxidation loss on the outer surface of the electrode. In recent years, in order to improve the smelting rate of electric furnaces, oxygen blowing has been widely used, which has led to an increase in electrode oxidation losses. In general, the oxidation loss on the outer circular surface of the electrode accounts for about 50% of the total electrode consumption.(3) Residual loss of electrodes or connectors. A small section of electrode or connector that is continuously used at the connection between

What aspects will endanger the use period of graphite board

First, the quality of the production and processing of graphite board is the direct cause of the life of the application of its application. Graphite board production and processing must be careful to reach the overall goal of the standard. For example, pre -immersing this level must be well -proportioned, so that its resistance is basically unremittingly consistent, so that the conductivity can be proportioned to prevent the entire production process from occurring in the process of production Some part is complete, but some of the erosion is serious, so that all personnel come out to consume.In the second place, the graphite board must have an excellent office environment, which is the fundamental to prolong life. During the entire production process, reduce the impact and clean up the office environment. It can check the power circuit on time, produce at the best temperature, and reduce the air oxidation of the gas to its air.In the end, high -quality graphite boards are used to im

Purification method of graphite

The flotation method is one of the conventional mineral purification methods that consumes less energy and reagents, and has lower costs. This is a major advantage of the flotation method for purifying graphite. However, when using the flotation method to purify graphite, it can only achieve a limited improvement in the grade of graphite. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomers, but also is not conducive to protecting the large flakes of graphite. Therefore, using flotation to further improve the graphite grade is not economical or scientific. To obtain high carbon graphite with a carbon content of over 99%, it is necessary to use chemical methods to purify the graphite.（1） Chlorination roasting methodThe low roasting temperature and low chlorine consumption of the chlorination roasting method greatly reduce the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to that after tr

Artificial graphite characteristics

Crystal structureNatural graphite: Crystal development is relatively complete, the graphization of scales graphite is more than 98%, and the graphitization degree of natural micro -crystal graphite is usually below 93%.Artificial graphite: The degree of crystal development depends on raw materials and thermal treatment temperature. Generally speaking, the higher the thermal treatment temperature, the higher the graphite. The artificial graphite produced by industrial production is usually less than 90%.Organizational structureNatural scale graphite: It is a single crystal, which is simpler in the tissue structure. There are only shortcomings in crystalline learning (such as defects, wrong positions, errors, etc.). The grains of natural micro -crystal graphite are small, the clutter between the grains is arranged, and there is a hole after the removal of impurities, which shows the same sex in the macro.Artificial Graphite: It can be regarded as a variety of materials, including graphi

Graphite powder from graphite manufacturers

Graphite powder produced by graphite manufacturers is a widely used industrial material, which is obtained by crushing, grinding, and screening high-purity graphite through rolling. The key to the type of graphite powder is the particle size, which varies from 50 to 30000 mesh. The more mesh the screen, the finer the particle size, and the higher the price. Previously, our country's technological strength could not be achieved, and high-end graphite powder relied on imports. However, at present, Chinese manufacturing enterprises have introduced cutting-edge overseas powder mills, which can produce fine graphite powder with global particle size and have been applied in many industries both domestically and internationally.Graphite manufacturers offer various types of graphite powder, including lubricating graphite powder, conductive graphite powder, nanotechnology graphite powder, high-purity graphite powder, and graphite powder screens with mesh sizes of 150, 425, 1000, 3000, 5000, 65

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.
