What are the main applications of graphite electrodes in?

(1) Used for electric arc steelmaking furnaces. Electric furnace steelmaking is a major user of graphite electrodes. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace,Utilize the high-temperature heat source generated by the arc between the electrode end and the furnace material for smelting.(2) Used for submerged arc furnaces. The submerged arc furnace is mainly used for the production of industrial silicon and yellow phosphorus, and its characteristic is that the lower part of the conductive electrode is buried in the furnace material,Arc is formed within the material layer and the heat energy emitted by the resistance of the furnace material is used to heat the furnace material. A submerged arc furnace with a high current density is requiredGraphite electrodes are required.(3) Used for resistance furnaces. The graphitization furnace for producing graphite products, the furnace for melting glass, and the electric furnace for producing silico

How to extract high -carbon graphite

The high -carbon graphite extraction method and the flotation method is low in the purity of minerals and the loss of reagents. This is the advantage of purifying high -carbon graphite. However, the application of floating and purifying graphite can only make the graphics of graphite unlimited improvement. For sheet -shaped graphite, not only can not solve its complete monomer, but it is not conducive to maintaining large hungusgogi. High carbon graphite must be chemically purified for graphite.(1) Pure method of high carbon alkali acidic acid. The carbon content purified by alkaline is more than 99%of the carbon content, which has the characteristics of less one -time investment, high product grade, and strong process adaptability. It also has a strong generality. The purity of non-metal minerals can use the advantages of alkali-acid method, and the alkali-acid method is the most commonly used method in my country today.(2) High -carbon graphite chloride and roasting method. The chlo

What are the key applications of graphite shells?

With the development of science and technology, graphite slowly turns into selected raw materials for mold production with its excellent physics and organic chemical characteristics. Graphite molds are generally used in various industries. Below I take the old iron to take a look at the key use of graphite mold!1. Rare metal forging and semi -continuous forging for graphite moldIn recent years, countries around the world have been marketing and promoting the situation of fusion metal materials and continuously (or semi -continuous) production and manufacturing bars or pipes. China has gradually selected this method at the level of copper, alloy copper, aluminum, aluminum alloy profiles. Artificial synthetic graphite is a continuous forging or semi -continuous forging as a rare metal. Manufacturing practice has proved that because of the selection of graphite mold shells, it has excellent thermal transmission performance (the heat transfer performance decided to condense the condensate

Differential needs of scales graphite in different fields

There are many types of domestic scale graphite resources and rich features, but the current domestic graphite mine resources are relatively simple. It mainly found that the natural types of ore, ore taste, main minerals and pulse ingredients, optionality, etc. It is simple, focusing only on the crystal shape of the crystal, the amount of carbon, sulfur content, and scales. Although there are huge differences in the characteristics and quality of graphite ore and fine powder in each scale graphite, they are not distinguished at all from the sperm powder logo. The classification system simply brings the high degree of homogeneity of the upstream raw materials of graphite in various places, covering the reality of its reality Application value, the following editors talk to you about the differentiated demand for scales graphite in different fields:This status quo has brought very prominent problems: on the one hand, the lower reaches of the scale graphite is very difficult and blind to

Graphite mineral classification

Graphite's process characteristics are mainly determined by its crystallization form. Crystal forms of graphite minerals have different industrial values and uses. Industry, according to the different crystals, divide natural graphite into three categories.1. Deep crystalline graphiteThe dense crystal graphite is also called block -like graphite. Such graphite crystals are obviously visible to the naked eye. The diameter of the particles is greater than 0.1 mm, which is concentrated in 0.1-1m/g than the surface area. This: Graphite is characterized by high quality. Generally, carbon content is 60-65%, and sometimes 80-98%, but its plasticity and slipperyability are not as good as scales.2. Scales graphiteGraphite crystals are scales; this is made of deterioration under high -intensity pressure, with large scales and fine scales. The characteristics of such graphite ore are not high, generally between 2 and 3%, or 10 to 25%. It is one of the best ore in nature. The floating, lubricabil

What is the application scope of industrial graphite powder

Excellent characteristics of graphite plates

Graphite plate is a good technical property, and its good properties are widely used in various industries. Due to the excellent chemical and physical properties of the product, it has gradually become a key raw material for making grinding tools. Graphite belongs to the raw material of graphite carbon. During the production process, alkaline resistant organic chemical compounds are added, and then subjected to high-pressure manufacturing and forming. After undergoing high-temperature heat treatment, production and processing are carried out, thereby reducing the porosity of graphite products, improving the relative density of products, and possessing good alkali resistance and wear resistance. Graphite plates have high-quality characteristics and are suitable for industries such as forging, metallurgy, and grinding tools. CNC lathe processing machines and equipment further enhance the overall production and manufacturing level, and consider the requirements for precision and surface

What should be paid attention to when processing refractory materials with flake graphite?

The application of scales graphite in rust protection

Scale graphite should be no stranger. The scales graphite is very wide, such as lubrication, conductivity, etc. So what are the applications of scales graphite in rust?Apply the scales graphite on a solid and then put it in the water. We will find that the solids that have been applied by the scales will not be wet by the water. Even if it is soaked in water, it will not be wet. The layer protective film is separated from the water from water, which is enough to indicate that the scale graphite is not soluble in water. Using the characteristics of graphite can be used as a good rust -proof paint, coated with metal chimneys, roofs, bridges, pipes, and can effectively protect the metal surface from corrosion of atmosphere and seawater, and has good anticorrosive rust and anti -anti -rust performance.This situation is often encountered in life. The connection bolt or steam pipe flange of the cleaning equipment is very easy to rust, which brings great trouble to maintenance and disassembl
