Tungsten Stream Mouth
The
tungsten stream mouth is as a special tungsten alloy with other refractory
metals. It mainly uses in rare-earth metal smelting, the induction furnace
heating element, the quartz glass smelting and so on, makes the high
temperature vessel.
In the glass and the
ceramic industry, the tungsten class mouth is a ceramic micro production very
essential part. The tungsten proportion is big, degree of hardness is big, the
heat conduction electric conductivity good, heat-resisting, wear-resisting,
anti-corrosive, has the low expansibility and the size stability under the high
temperature. The tungsten melting point is highest when all metals (reaches as
high as 3380 degrees Celsius), the steam tension to be lowest, the tensile
strength is highest (1650℃),
and its antiseptic property is good, the majority inorganic acid are very small
to its corrosion.
