Solar Manufacturing Ships Sintering Vacuum Furnace
Due to the extremely high maximum temperature this end user desired and the need for superior temperature uniformity, the hot zone is super insulated with eight layers of 0.5-inch-thick high-purity graphite felt insulation for superior energy efficiency. The insulation pack is protected by a hot face of 0.040-inch-thick Flex Shield, a durable, flexible carbon-fiber-reinforced graphite foil. Thin graphite heating elements are mounted cylindrically in the hot zone and divided into multiple trim zones. The weight capacity of the graphite hearth is 2,000 pounds.
The external gas-quenching system utilizes a high-capacity copper heat exchanger, 150-HP drive motor and a radial blade fan for high-velocity gas quenching through unique “forward tapered” graphite nozzles. A 20-inch Varian diffusion pump allows for high-vacuum performance of 1x10-5 Torr.
