But not to mention graphite electrode suppliers the currently used isotropic high-purity graphite products will be eliminated in the future and replaced by carbon-carbon fiber composite materials. In addition, there are water, asphalt, CO2, H2, CH4, N2 and other gas parts. In the semiconductor industry, high-purity graphite materials are widely used in the heating system of the Czochralski single crystal furnace. But at the same time, we also need to see that while China's large-scale, high-purity isotropic graphite market is rapidly increasing, China's manufacturing technology in this respect still has some unsuitable aspects, and the technology is still very large with advanced foreign countries. 1. ﹙2﹚

Carbon-carbon fiber composite materials have a long production cycle in the manufacturing process, and the mass production speed is low. Such graphite products currently occupy a very small part of the carbon graphite material product group used in the semiconductor and photovoltaic industries.

Examples of application fields of carbon-graphite: steel industry, non-ferrous metal industry, high-temperature technology, automotive industry, racing / boating supplies, sports equipment, industrial fabrics, aerospace, satellite technology, defense technology, maritime technology, energy industry, solar technology , Power generation technology, nuclear technology, chemical industry, environmental protection, pharmaceutical technology, fertilizer industry, mechanical engineering, process equipment, sealing technology, tool manufacturing, plastics, glass ceramics, papermaking, construction technology, household appliances, electronics industry, semiconductor technology,

Electrical engineering technology, medical industry, measurement and test industry. Important work that is imperative. It must be a material that is resistant to high temperatures, low density, low thermal conductivity, less heat storage, good thermal insulation, less outgassing, light weight, and low expansion coefficient. application. The important raw material required for solar cell silicon wafers, ingot polycrystalline silicon, began to use a large number of high-purity, high-quality graphite materials in the ingot furnace of its production device.

The changes in coke consumption in the above countries fully reflect the development and changes in the country's steel industry, mainly in the iron-smelting sector. For example, Japan ’s coke consumption remained “strong” for a long period from 2000 to 2007, reflecting its status as a world ’s largest iron-smelting production system and the steady development of pig iron production in the context of the rapid development of the world ’s steel industry;

Coke consumption generally shows a downward trend, reflecting that its steel industry pays attention to the development of electric furnace steelmaking, and the overall consumption of coke in the ironmaking process gradually decreases. Further calculated the net exports / imports of the top ten coke consuming countries in the world from 2000 to 2007, as shown in Figure 4. It can be seen that among the top ten coke consumer countries, except Poland, which is a net exporter, the remaining nine countries are all net importers, and some countries even import large quantities.

The above phenomena all indicate that for the world's major steel-producing countries, coke resources are showing greater scarcity, and this scarcity is becoming more and more obvious. III. Production analysis of the world's major coke producers In other major steel producing countries and regions except China, about 90% of coke production capacity is distributed within the steel companies. Therefore, the world's major coke companies are the major steel companies. The following uses Arcelor-Mittal and American Steel as examples for analysis. 1.

However, we can optimize the angle of the tool, select materials and improve the structure of the ordinary coating on the basis of the ordinary tool. To a certain extent, it can still be applied in graphite processing. The geometric angle of diamond-coated tools is different from that of ordinary coated tools. Therefore, when designing diamond-coated tools, due to the particularity of graphite processing, the geometric angle can be appropriately enlarged and the chip flute can also be enlarged without Reduce the wear resistance of cutting edge. For the ordinary TiAlN coating, although its wear resistance is significantly improved compared to uncoated tools, compared with diamond coating, the geometric angle of graphite should be appropriately reduced when processing graphite to increase its wear resistance Sex. For diamond coatings, many coating companies in the world have invested a lot of manpower and material resources to research and develop related technologies.
