High-temperature furnaces can reach temperatures of up to 2800°C. We have developed shield packs made of refractory metals to help cool things down.
Our side shieldings, top shieldings, and bottom shieldings made of molybdenum, tungsten, ML, and stainless steel are heat-resistant with exceptional dimensional stability. We can adapt the shielding concept specifically for use in your furnace. Depending on your requirements, we can manufacture riveted, overlapping, and joint shields in any size you need.
We have designed shieldings made of an optimized quantity of W, ML, and Mo sheet layers to keep the heat loss of your furnace as low as possible during the process. A crucial factor here is the thermal radiation exchange between the sheet layers as well as the extremely low emissivity of molybdenum. Furthermore, our shieldings made of molybdenum, tungsten, and their alloys have a low specific heat capacity, enabling fast heating and cooling rates at short evacuation times, high process purity (graphite-free shielding), and short process cycle times. This makes them extremely well suited for use in the high-vacuum and ultra-high vacuum range. Using new, tailor-made designs, we can optimize the shieldings for your application in terms of weight and energy costs.
