Vertical Vacuum Quenching Furnace
The Vertical Bottom Loading Vacuum Furnaces are external quench, vacuum heat treating and brazing furnaces generally designed for high production commercial, aerospace, and captive heat treating shops. They are high temperature, high vacuum, batch-type furnaces with electric resistance heating elements. Designed for heat treating, hardening, brazing, stress relieving, normalizing, annealing, tempering, sintering, homogenizing, degassing, diffusion bonding, creep forming, low pressure carburizing.
Graphite Hot Zone Construction:
Operating temperature: 2400°F
Maximum temperature: 2500°F
Temperature uniformity: ±10°F
Survey temp points at 1000°F / 1500°F / 2100°F
Insulation: multiple layers of 1/2” thick high purity rayon graphite felt
Hot Face: one layer of 0.070” thick CFC², or other materials upon request
Heating elements: rugged segmented, curved graphite bands or Molybdenum bands, supported with proprietary design to reduce metallization of insulation materials and increasing the ease of maintenance
Hearth: Molybdenum or graphite hearth rails and hearth posts
Support Structure: insulation and heating elements are mounted on a heavy duty 304 stainless steel fabrication with heavy duty, back up shields of 0.090” thick
All-Metal Shielded Hot Zone Construction:
Operating temperature: 2400°F
Maximum temperature: 2500°F
Temperature uniformity: ±10°F
Survey temp points at 1000°F / 1500°F / 2100°F
Insulation: combinations of molybdenum and/or stainless steel sheet metal
Other shielding materials are available depending on the application and temperature requirements
Hot Face: Lanthanated Molybdenum hot face increases hot zone life expectancy
Heating elements: rugged segmented, curved graphite bands or Molybdenum bands, supported with proprietary design to reduce metallization of insulation materials and increasing the ease of maintenance
Hearth: STA hearth rails for strength at high temperatures
