In large-scale industrial production, it is difficult to reach the high temperature of 2000. However, in the process of high-temperature heat treatment and transformation, when the temperature reaches 2000 ℃, the thermal conductivity and conductivity of carbon change greatly. At this temperature, it has been able to achieve the good characteristics of graphite, with good thermal conductivity and conductivity. Therefore, at 2500 ℃, the heat-treated artificial graphite has 16 times higher thermal conductivity and 4 times higher electrical conductivity than the carbon material, and its structure is more lubricating and easier to process than the carbon material.
In this way, the main technical properties of the artificial graphite can be similar to that of the natural graphite artificial graphite. There are three methods, namely extrusion molding, ramming molding and balanced compression molding. Different molding methods affect the direction of mechanical properties of graphite. Therefore, different materials of graphite products with different forming methods should be used to make different purpose graphite equipment. One cubic meter of sand weighs more than one cubic meter of stone. Because the gap is smaller, the smaller the particle size, the higher the density of graphite products, and the better the strength and other indicators.
Graphite electrode is easy to process, and the processing speed is faster than copper electrode. For example, when using milling technology to process graphite, its processing speed is 2-3 times faster than that of other metals, and no additional manual treatment is needed, while copper electrode needs manual grinding. Similarly, if high-speed graphite products processing center is used to make electrodes, the speed will be faster, the efficiency will be higher, and there will be no dust problem. In these processes, choosing the right hardness tool and graphite can reduce the wear loss of the tool and the damage of the electrode. If the milling time of graphite electrode is compared with that of copper electrode, graphite is 67% faster than that of copper electrode. In general, the machining speed of graphite electrode is 58% faster than that of copper electrode. In this way, the processing time is greatly reduced, and the manufacturing cost is also reduced. Therefore, our purchasing personnel need to hold many models of graphite products in the market, look at the bumpy component, the color and other aspects to see good results, because now the technology is more advanced, which is also helpful to improve the performance of the products.
