We know that tungsten crucible has many valuable properties, such as extremely high melting point, low vapor pressure, low expansion, dimensional stability at high temperature, excellent high-temperature mechanical properties, special electrical properties, and so on. It is these valuable properties of tungsten that make tungsten a basic material in today's high technology, an indispensable material in national defense construction, and a material closely related to people's quality of life. Therefore, tungsten plays an important role in the national economy. It is the world's largest tungsten resource country and the world's largest producer of tungsten products. According to the statistics of the Tungsten Association in 2003, the actual output of tungsten products reached about 2,570 tons, accounting for 15%-16% of my country's tungsten consumption. Processed products have developed by leaps and bounds.
What are the technologies and contents of deep processing of tungsten materials? It mainly includes the following aspects:
1. Forming, transforming different tungsten materials into various shapes by bending, which is the forming process. The specific methods of tungsten material processing include cold forming, hot forming, and high-temperature forming.
2. Machining, as well as joining, including welding and other aspects, as well as surface treatment. Through the integration of the above technologies, the tungsten processed material can be turned into the required components or components for use.
For example, the tungsten crucible, the heating element of the tungsten plate, is actually a combination of the above technologies. For example, if we want to shape the tungsten plate, we need to form a shape, and we need forming technology, and tungsten and tungsten must be welded together. , There is a welding technology, tungsten needs to be cut into this shape through the technology of electric spark cutting, so it is a product of various technologies, this drawing also reflects the technology of tungsten on the heating body, in addition to electrochemical cutting In addition to the technology and sheet forming technology, there is also a weaving technology of tungsten wire mesh. The tungsten wire mesh weaving technology must be connected to the power supply. It is necessary to weld the tungsten wire mesh and the electric claws together by welding technology The heating element of the entire tungsten wire mesh, this heating element is currently the first component of the temperature to reach the metal, so these things are a combination of different technologies.
