Frequently Asked Questions
FAQWhat is the temperature uniformity of the NVPT series vacuum tempering furnace?
The NVPT series achieves a high furnace temperature uniformity of ±5℃. This is made possible by incorporating a multi-zone independent temperature control system combined with a precise PID control algorithm, ensuring consistent material microstructure and minimizing performance variations.
Does the equipment prevent oxidation during the heating process?
Yes. By heating the workpiece within a vacuum range of 10-2 to 10-6 mbar, the furnace effectively prevents oxidation and decarbonization. This process guarantees a smooth surface finish and keeps the internal material properties free from external impurities.
Can the dimensions and parameters of the furnace be customized?
Absolutely. We support complete customization of the effective working area size, maximum operating temperature, working vacuum levels, and other critical parameters to perfectly fit your specific production demands and layouts.
What type of cooling system does the NVPT series use?
The furnace features an advanced built-in internal cooling system. This design eliminates the need for external cooling processes, allowing the treated workpieces to transition directly and safely to subsequent production steps, significantly reducing cycle times.
How is the furnace controlled and monitored?
It features an integrated PLC system complete with a program controller or computer interface, touch screen, and data recorder. This allows for real-time monitoring of critical parameters like vacuum levels, temperature, and pressure, while also supporting remote fault diagnosis and process traceability.
