Standard vacuum furnace in a 1315 ☌ operating temperature, the heat shields are two layers of molybdenum sheet, outside the three-tier stainless steel sheet within the composition. Molybdenum heat shield has the following characteristics: linear thermal expansion coefficient is small, easy processing, low thermal conductivity, small specific heat. Molybdenum at 1200 ° C is still high strength. Its melting point is 2620 ℃, inferior to tungsten, tantalum, but the density was compared with a much lower specific strength (strength / density) is greater than metals such as tungsten, tantalum, weight very critical applications, is valid. open)] was the best match, making it the best choice for thermal shock and thermal fatigue.open) and specific heat of 0.276 kJ / (kg.
Metal molybdenum thermal conductivity of 135 W / (m compared with tungsten ease of processing linear thermal expansion coefficient is small. Molybdenum heat shield is very similar to the nature of the molybdenum and tungsten in its boiling point and electrical properties. In an all-metal thermal field, the heat shield by the multi-layer metal plate, to reserve a certain space between each floor insulation board. Molybdenum metal and graphite can also be used as vacuum furnace insulation parts. In order to ensure the quality of products, we adopt international safety standards and technologies to continuously improve and perfect the product performance. We have a scientific internal organization and a perfect, efficient and reasonable operation system to make our company more adapt to the needs of market competition. Proactiveness is our consistent development wisdom, while sound and scientific management is the guarantee of our achievements and sustainable development. Our mission will be to become an innovative supplier of high-tech digital and communication devices by furnishing benefit added structure, world-class manufacturing, and service capabilities for Tungsten Carbide Cutting Tools For Bore Machining And End Mills, Tungsten Plates, Heavy Tungsten Alloy Balance Weight For Crankshaft.
