Product Description
Tungsten And Molybdenum Heat Shield For Vacuum Furnace
1. Description of Tungsten And Molybdenum Heat Shield For Vacuum Furnace:
Molybdenum metal and graphite can also be used for insulating parts of vacuum furnaces. In an all-metal thermal field, the heat shield is composed of multiple layers of metal plates, with a certain space reserved between each layer of heat shield.Molybdenum and tungsten have a lot of the same characteristics as each other, including a high boiling point, excellent electrical conductivity, and a low linear thermal expansion coefficient that makes processing molybdenum easier than tungsten.
The thermal conductivity of metallic molybdenum [135 W/(m·K)] is optimally matched with the specific heat [0.276 kJ/(kg·K)], making it a natural choice for thermal shock and thermal fatigue resistance. Its melting point is 2620°C, second to tungsten and tantalum, but its density is much lower, so its specific strength (strength/density) is higher than that of tungsten, tantalum and other metals. efficient. Molybdenum still has high strength at 1200℃.
Molybdenum heat shield has the following characteristics: small coefficient of linear thermal expansion, easy processing, low thermal conductivity, and small specific heat.
2. Size and Tolerance of Tungsten And Molybdenum Heat Shield For Vacuum Furnace:
