Three-chamber oil and gas double quenching vacuum furnace

Introduction to three-chamber oil and gas dual quenching furnace:
3 rooms double oil and gas quenching vacuum quenching furnace is two quenched in oil and gas quenching vacuum furnace, on the basis of the development of multi-function vacuum heat treatment equipment, has a wide application efficient environmental protection and energy saving means low investment costs. The effective utilization rate of the equipment was significantly improved, and the energy saving (30% - 50%). It is mainly used for the vacuum bright quenching and titanium alloy of steel, tool steel, bearing steel, spring steel, stainless steel and other materials.


Three-chamber oil and gas double quenching vacuum furnace


Characteristics of three-chamber oil and gas dual quenching furnace:
 Automatic program control, stable operation, good value of process, (optional)
 Strong process library support, use the simulation process to automatically fetch data, realize one-click operation.
 Reasonable space modularization design, quick evacuation and minimum quenching gas.
 Using high quality graphite felt/metal screen, heating element 360 degree radiation heating.
 The air quenching chamber is evenly staggered and distributed 360 degree circulation cooling.
 Large area heat exchanger is cooled faster in the same pressure condition.
 Internal and external circulation fan, can realize vacuum state startup.
 Open or closed internal circulation water cooling system.
 Vacuum partial pressure/low temperature convection heating/grade isothermal quenching.
 The quenching oil circulation adopts electromagnetic drive and heat transfer device.
 Reliable feeder transfer system.
High vacuum middle gate valve ensures independent work of vacuum chamber.
