Isostatic pressing graphite: an outstanding material in multiple fields

clay graphite crucible

Isostatic pressing graphite is a multifunctional material that plays an important role in different fields. Below, we will provide a detailed introduction to the different uses of isostatic pressing graphite in several major fields to understand its widespread application and key value in modern industry.

 

1. Applications in the nuclear energy industry

Nuclear reactors are the core of the nuclear energy industry, requiring control rods to adjust the number of neutrons in a timely manner to control nuclear reactions. In high-temperature gas-cooled reactors, the materials used to make control rods need to remain stable in high temperature and irradiation environments. Isostatic pressing graphite has become one of the ideal materials for control rods by combining carbon and B4C to form a cylinder. Currently, countries such as South Africa and China are actively promoting the research and development of commercial high-temperature gas-cooled reactors. In addition, in the field of nuclear fusion reactors, such as the International Thermonuclear Fusion Experimental Reactor (ITER) program and Japan's JT-60 device renovation and other experimental reactor projects, isostatic graphite also plays a key role.

 

2. Application in the field of electric discharge machining

Electrical discharge machining is a high-precision machining method widely used in the field of metal molds and other machining. In this process, graphite and copper are commonly used as electrode materials. However, the graphite electrodes required for discharge machining need to meet some key requirements, including low tool consumption, fast machining speed, good surface roughness, and avoidance of tip protrusions. Compared to copper electrodes, graphite electrodes have more advantages, such as lightweight and easy to handle, easy to process, and less prone to stress and thermal deformation. Of course, graphite electrodes also face some challenges, such as being prone to dust generation and wear. In recent years, graphite electrodes for ultrafine particle discharge machining have emerged in the market, aiming to reduce graphite consumption and reduce the detachment of graphite particles during discharge machining. The marketization of this technology will depend on the production technology level of the manufacturer.

 

3. Non ferrous metal continuous casting

Non ferrous metal continuous casting has become a common method for producing large-scale copper, bronze, brass, white copper and other products. In this process, the quality of the crystallizer plays a crucial role in the qualification rate of the product and the uniformity of the organizational structure. Isostatic pressing graphite material has become an ideal choice for making crystallizers due to its excellent thermal conductivity, thermal stability, self-lubrication, anti wetting, and chemical inertness. This type of crystallizer plays a crucial role in the continuous casting process of non-ferrous metals, improving the crystallization quality of the metal and preparing high-quality casting products.

 

4. Applications in other fields

In addition to the nuclear energy industry, discharge machining, and non-ferrous metal continuous casting, isostatic pressing graphite is also used in the manufacturing of sintering molds for diamond tools and hard alloys, thermal field components for fiber optic wire drawing machines (such as heaters, insulation cylinders, etc.), thermal field components for vacuum heat treatment furnaces (such as heaters, bearing frames, etc.), as well as precision graphite heat exchangers, mechanical sealing components, piston rings, bearings, rocket nozzles, and other fields.

 

In summary, isostatic pressing graphite is a multifunctional material widely used in various fields such as nuclear energy industry, discharge machining, and non-ferrous metal continuous casting. Its excellent performance and adaptability make it one of the indispensable materials in many industrial fields. With the continuous development of technology and the increasing demand, the application prospects of isostatic pressing graphite will be broader, bringing more opportunities and challenges to the development of various industries.
