China is a country with rich tungsten
resources, over half a century, made significant contributions to the
development of the world's tungsten industry. Especially in recent decades,
China's industrial development has moved from exporting tungsten concentrates,
importing of tungsten products, tungsten processing products and gradually
developed into a basically meet the domestic demand, and can develop into a
large variety of tungsten products export industry country. This is not only
fundamentally changed the situation of China's tungsten industry, and more
successful for the development of China's defense industry and national
economic development has made important contributions. Tungsten processed
products in multiple areas of both production capacity or production are among
the highest level in the world, to become truly world-recognized major
industrial countries, but in some aspects of tungsten processing technology
with the world advanced countries there is still a gap, to become a true world
power tungsten processing technology needs make great efforts.
Tungsten products in the important role of
nation-building
Processing of tungsten materials including
tungsten carbide, tungsten alloy, tungsten wire, tungsten electrode, the scale
of production of these materials and properties at or near the world level, to
better meet China's national economic construction and national defense needs,
has made significant contributions to the Chinese the rapid development of
national economic construction and national defense modernization enable China
to a new attitude based on the world of the forest.
Tungsten-based alloys in the construction
of national defense and the important role of the national economy
(1) In the aerospace industry applications.
China developed the first generation of tungsten heavy alloy performance good
in the 1960s, since immediately after the birth of self-developed China's first
artificial satellite navigation device has been successfully applied, then this
new material has the first in China an intercontinental missile and developed
by a variety of new fighters, helicopters, has been successfully applied.
Developed to meet the needs of Chinese communications satellite, but also
successfully developed a new type of density up to 18.5g/cm3 high proportion of
tungsten-based alloys. A variety of high-performance W-Cu alloys in the rocket
(missile) combustion chamber, nozzle, throat, rudder and other parts of the
development of high temperature has been applied.
(2) Military industrial applications. China
has successful developed the W-Ni-Fe heavy alloy, provides of a variety of
wear, shaped charge of the development a key material. W-Ni-Cu heavy alloys
also play an important role in doing gyrorotor high proportion of material in
China's first nuclear submarine of the research and development.
(3) In the civilian industry and nuclear
industrial applications. In the nuclear power industry, used for nuclear
reactor insulation and shielding materials, tungsten heavy alloy has a good
prospect. In civilian industry, high-density tungsten alloy has been more
widely used; mobile phones and golf oscillator rod weight will be a wide range
of products. Processing done in the electric performance of the anvil block
material to make electrical upsetting of hundredfold increase production
efficiency, has significant economic benefits.
In summary, the development of tungsten
processing industry does not only play a very important role in building on the
national economy, also has a significant impact on the modernization of
national defense.
