Top Charging Vertical Vacuum Furnace - High Precision Heat Treatment Equipment from China Suppliers and Factory
Characteristic
01
Electric or hydraulic drive furnace cover lifting, with a special lifting system, heavy workpieces quickly and smoothly into the furnace, reduce the risk of manual intervention and bump.
Heating the workpiece under different vacuum degree (10-2~10-6 mbar) to avoid surface oxidation and decarbonization and ensure pure and stable process environment.
Multi-zone independent temperature control, combined with PID algorithm, to achieve ±5℃ furnace temperature uniformity, with good temperature control accuracy, to meet the needs of large workpiece consistency processing.
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 long service life.
Through different cooling inert gas (nitrogen, argon, helium) and under different cooling pressure, combined with high speed and large flow fan to quickly cool the workpiece, cooling speed is controllable.
Can choose the cooling gas flow direction and air flow reversal time, combined with high efficiency heat exchanger, significantly improve the cooling uniformity, reduce the thermal stress deformation of parts.
Enhanced furnace structure + multiple safety protection, in line with international safety standards, equipment life of more than 20 years.
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.
