Selection and use of graphite

What are the choices of is used for refining, and usually the temperature is extremely high. Therefore, the raw materials for manufacturing should have high refractory resistance and have a strong high temperature resistance coefficient. There are also sufficient strength of ingredients. If the impact of high temperature, etc. during the smelting process, there will be wear. Therefore, if the strength of the raw material is not high, it is likely that the more waves will be used, and the more toughness will be lacking. The contraction coefficient must be small, and the temperature changes sharply without deformation and breaks. There must be not to afford the chemical response with the melted metal in the selection of materials, and the high temperature resistance of chemical metals should be high. Loss. When the melting metal is demanded at high temperature, the selection of should ensure that chemical stability at high temperature should be learned. It can be seen that there are a

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

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

What are the advantages of high pure graphite?

Simplified graphite is an inorganic non -metallic material. High -pure graphite is a common advantage in processing and manufacturing structure casting molds, exercise of high -pure metal, sintering mold, metal coating, and transmitting electron tube. High pure graphite has corrosion resistance, the substrate is uniform and small, delaying the degree of corrosion of the product. In addition, it also has high thermality. High -content fixed carbon ensures good thermal conductivity, shorten the dissolution time, and significantly reduces energy consumption. In particular, its quality stability, the manufacturing technology and quality assurance system of high -voltage molding methods fully ensure quality stability. If graphite molds and graphite processing products of various shapes and uses can be achieved in the metallurgical industry, graphite with accuracy and roughness can be processed. High -pure graphite is specially designed according to the conditions of rapid heating and fast

Do you know the development history of graphite?

Graphite occupies an important position in the industry, and because of its good performance, graphite is widely used in many industries, and its use effect is good, so it is loved by users. Some basic knowledge of graphite must be known to everyone. The following is the development history of graphite. Presumably very few people know this. So today, let us take a closer look. The following is the introduction made by graphite manufacturers.Graphite is a kind of carbide accidentally discovered in the laboratory by Acheson of the United States in 1891 when he was conducting molten diamond experiments. At that time, it was mistaken for a mixture of diamonds, so it was named emery. The industrial method of smelting graphite, also known as the Acheson furnace, is still in use today. The electric resistance furnace with carbonaceous material as the furnace core generates graphite by heating the mixture of quartz SIO2 and carbon.Several events about graphiteGraphite was first discovered in

Special graphite for electric spark processing

Electric spark processing is a new type of processing process in the mechanical manufacturing industry. Electric spark processing can process many metals with large hardness and can be processed. Copper materials can also use graphite materials. Graphite materials used for electrical electrodes used for electrical sparks must have the following conditions:(1) The structure is dense and uniform in tissue, and there should be no coarse particles and large pores;(2) There is a high mechanical strength and good processing performance.
