Application

Tungsten, the melting point of which is 3420 °C, has excellent high-temperature strength and good corrosion resistance to molten alkali metals and couples. Its high heat resistance allows all tungsten products to work properly in very high temperature conditions. Tungsten heat shields are widely used as insulating elements of high temperature furnaces and as heaters at the next layer of insulation. High melting point and stable characteristics at high temperature are widely used in the construction of ovens, where low pollution sapfirovaya tungsten glass insulation provides higher quality of the equipment. In this case the temperature field is more uniform and heat loss when heating do not exist.

Production

Billet tungsten heat shields get in the high-temperature technology of hot rolling, after which the surface tungsten sheet almost reaches the theoretical density of the base metal. Then, after finishing the cleansing treatment to achieve a mirror surface state. Thanks to the excellent heat transfer in a vacuum environment, tungsten sheet possesses the minimum thermal deformation and retains its original shape. Typically, tungsten heat shields are manufactured with sizes of 0.05 to 50 mm in thickness, from 50 to 500 mm in width, and 100 to 1500 mm in length.
