Pre-vacuum chamber furnace

Forvacuum box-type furnace is a single-chamber structure, the workpiece is heated under a protective atmosphere, the temperature of the heating chamber atmosphere heat treatment process is controlled by computer PLC, without manual intervention, will minimize human disturbance factors, is an automated a high degree of heat treatment equipment.
Pre-vacuum chamber furnace design requirements:
Pre-vacuum chamber furnace designed according to customer requirements, mainly used for stainless steel precision castings annealing, the device considers factors:
1. Production capacity: customized according to customer requirements.
2. Operating temperature: commonly used temperature of 850 ° C -920 ° C maximum temperature 950 ° C
3. Smart meter + SCR temperature control system to improve the control precision, saving energy (more than 30% energy saving than the on-off), reducing the impact on power.
4. Additional protection medium injection device and furnace pressure, the injection volume of the dosing medium to protect the workpiece is not oxidized.
5. A four-link door seal structure, with water cooling jacket and silicone rubber sealing device to ensure that the protective gas in the furnace is not compromised, to ensure that the pressure in the furnace, the heat loss is not easy.
6. Using the drag-lift type of materials into and out of institutions, to reduce the weight of the material basket, to improve the life of the material basket, reducing costly heat-resistant steel consumption.
7. Heat-resistant steel mixing fans, the furnace temperature uniformity up to ± 5 ° C (air furnace), to ensure product quality.
8. Imports of the light impervious C brick, heated indoor layer to reduce heat loss, further energy savings.
