1. Product Name: Three Chamber Gas and Oil Double Quenching Vacuum Furnace of Vacuum Heat Treatment Furnace Series
2. Model: Q433-Q1266
3. Usage: Vacuum bright hardening die steel, tool steel, bearing steel, spring steel, stainless steel and titanium alloy materials, magnetic annealing solution and aging sinter brazing and other process
4. Equipment Introduction:
The furnace is based on both oil quenching furnace and gas quenching vacuum furnace, on the development of multi-functional vacuum heat treatment equipment, with energy-efficient and environmentally friendly use a wide range of investment and low cost. Effective utilization of equipment significantly increased, an energy-saving (30% --- 50%). The main application of vacuum bright hardening die steel, tool steel, bearing steel, spring steel, stainless steel and titanium alloy materials, magnetic annealing solution and aging sinter brazing and other process
Features:
★ reasonable space of modular design, fast evacuation and minimal quenching gas
★ Use high-quality graphite felt / metal screen optional, heating radiant heating element 360,
★ gas quenching nozzle staggered evenly distributed 360 degree loop cooling
★ large heat exchangers, cooling faster at the same pressure conditions
★ external circulation fan, can achieve a vacuum start
★ within open or closed cycle cooling system
★ vacuum partial pressure / low temperature convection heating / grading isothermal quenching function
★ quench oil circulation and heat transfer using electromagnetic drive means
★ reliable skip transfer system
★ middle high vacuum gate valve to ensure that each vacuum chamber to work independently
