PQS Small Vacuum Furnace - China Suppliers & Factory for Advanced Quenching, Annealing, and Solution Treatment
characteristic
01Heat the workpiece under different vacuum (10-2~10-6 mbar) to avoid surface oxidation and decarbonization and ensure the purity and finish of the material.
Partition independent temperature control, combined with PID algorithm, to achieve ±5℃ furnace temperature uniformity, with good temperature control accuracy.
Through different cooling inert gas (nitrogen, argon, helium) and under different cooling pressure, combined with high-speed fan to quickly cool the workpiece, cooling speed is controllable.
The heating chamber is made of graphite composite material or all-metal structure (such as molybdenum heating elements and metal heat insulation screen), which is resistant to high temperature and high pressure airflow and has a long service life.
Low pressure gas quenching technology, compared with oil quenching or water quenching, reduce deformation and residual stress, suitable for small thin wall or complex shape parts.
Support heating, insulation, cooling multi-stage automatic control, can be preset complex heat treatment process.
Integrated PLC, with program controller or computer interface, touch screen, recorder and other real-time monitoring furnace vacuum degree, temperature, pressure and other data, support remote fault diagnosis and process tracing.
The whole equipment adopts miniaturized structure design, suitable for laboratory or small batch production, optimize space utilization, low energy consumption, flexible operation and so on.
