China NVPT Type Vacuum Tempering Furnace - High-Performance Heat Treatment Factory & Suppliers
Characteristics
01Heat the workpiece under different vacuum degree (10-2~10-6 mbar), prevent oxidation and decarbonization, ensure the surface of the workpiece is smooth, and ensure that the internal performance of the material is not interfered by external impurities.
Graphite heater or high resistance alloy heating element, fast heating speed, high temperature resistance, long life, with high efficiency insulation layer design, significantly reduce energy consumption, effectively shorten the tempering cycle, improve production efficiency.
Adopt multi-zone independent temperature control system, combined with PID algorithm, the furnace temperature uniformity can reach ±5℃, ensure the uniform change of material microstructure, avoid performance differences.
Equipped with built-in convection heating function to achieve efficient transmission and uniform distribution of heat, so that the equipment can operate stably in the low temperature area, accurately regulate the temperature, and meet the diversified process needs.
Equipped with advanced internal cooling system, no additional cooling treatment is required, which can directly and safely enter the subsequent operation process, greatly improving production efficiency.
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 opening mode of the furnace door is flexible (such as rotary type, vertical lifting type), which can be perfectly adapted to the automatic production line and effectively improve the overall production efficiency of the equipment.
