China VBL Bottom Charging Vertical Vacuum Furnace - High Performance Heat Treatment Equipment from Reliable Suppliers & Factory
characteristic
01Bottom lift loading system with vertical furnace, reduce floor space, support heavy workpieces efficient loading and unloading, reduce manual operation intensity.
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.
The load bearing table of the processing parts can be rotated during heating and cooling, which can ensure the best temperature uniformity and effectively control the deformation of the 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.
