The anti-seismic tungsten wire
With the progress of science and technology and the development of the society, the anti-seismic tungsten wire appeared, the quality of anti-seismic tungsten wire also be put forward more strict requirements. At high temperature, its anti-seismic performance of aseismatic tungsten filament with general process is not ideal, the forming of tungsten wire is poor, it is easy to break, the filament is easy to be out of shape and the distribution of luminosity is uneven. Therefore, optimizing the production process and improving the production technology to produce aseismatic tungsten wire with good high-temperature performance and excellent processing performance have important practical significance.
The aseismatic tungsten wire is named according to the normal temperature and high temperature aseismatic characteristics of tungsten wire. It is a kind of production with special properties in tungsten materials, it not only has high temperature sagging resistance and good winding property of common tungsten filament, but also it has very high aseismatic and shocking resistant performance. The other important application areas of aseismatic tungsten wire is in various tube as cathode heating wire, the annual consumption is at least 600 million meters. With the development of the world automobile, electronic industry and other industries, these numbers are expanding every year. According to statistics, in 1999 the domestic market demand is 21.4 billion meters, according to the annual growth rate of 8% to calculate, the domestic demand will reach 31.8 billion meters in 2005, its output value will increase from 31.4 billion yuan in 1999 to about 51.4 billion yuan in 2005.
The development of tungsten wire in the future is good, the tungsten wire produced by Zhengzhou Sanhui is highly praised by most of users, it also will become effective aseismic tungsten filament in the future.
