Tungsten Heating Chamber
It is worth noting that when the temperature is higher than 500 ℃, tungsten will oxidize, so tungsten parts should be used in vacuum or inert environment.
Product Introduction
1. product name: Tungsten heating chamber
Tungsten heating chambers are generally devices composed of heating elements and accessories. A glass fiber reinforced refractory fiber layer is wound around the multi-strand resistance wire stranded wire, and a metal wire reinforced refractory fiber layer is woven outside the refractory fiber layer, which is tightly combined and distributed along the entire length of the resistance wire stranded double-layer cladding layer and its center The resistance wire stranded wire forms an integral direct heating unit that can be bent at will and can be in close contact with the heated object. The metal wire knits together a plurality of side-by-side monomers horizontally to form a braided high-temperature electric heater that can be directly wrapped around the heated object and used directly.
2. Tungsten is a kind of refractory metal with a high melting point (3410°C), high density (19.35g/cm3), high hardness, high strength, low coefficient of thermal expansion, good heat resistance, and good corrosion resistance. The overall performance of the tungsten heating chamber is better, which is mainly manifested in good heat-proof effect, strong heat resistance, and long service life, that is, in an environment of thousands of degrees Celsius, the tungsten heating chamber is not easy to deform.
3. Tungsten heat shields are generally made by riveting, which can be butted or overlapped. Corrugated plates, U-shaped grids, or spacers can be used between each layer of screens, and they are fixed with tungsten wires and screws.
4. The side panels and upper and lower cover panels of the vacuum furnace can be made of tungsten. Compared with thermal insulation components made of other materials, components produced with tungsten materials have better thermal protection and can block thermal convection more effectively.
