Vacuum or atmosphere tube furnace provide a vacuum, controlled atmosphere and high temperature experimental environment, applied in semiconductor, nanotechnology, fiber and other fields.
1. Quick connection flange structure is adopted for gas path connection, which is convenient for loading and unloading, and can be completed with only one clamp.
2. The furnace is made of polycrystalline mullite fiber by vacuum adsorption, with uniform temperature field and energy saving of more than 50%.
3. Independently developed air diversion heat insulation technology ensures the service life and constant temperature effect of all parts in the box.
4. Start the electric furnace, and the exhaust fan will run automatically at the same time. After the test, the exhaust fan will continue to run until the temperature of the furnace body is lower than 60 ℃, and the exhaust fan will stop automatically, effectively protecting the surface of the furnace body.
5. The gas circuit assembly is made of 316 stainless steel of food grade, with good corrosion resistance, atmospheric corrosion resistance, high temperature resistance, and non-magnetic.
6. Automatic power-off, over temperature protection and leakage protection to ensure the safety of use.
7. Imported program temperature control system, 4 curves, programmable 40 segment program temperature control, touch screen is 7 inch screen, built-in 50 formulas, 50 programs, formula name can be set by users, formula can be added, deleted and transferred at will.
8. The circuit adopts continuous heating output mode, double circuit power supply, strong and weak current wiring separately, which improves the stability of the system.
9. The heating module adopts DC signal to adjust the output power, so as to avoid the interference of induction current to the control signal.
10. Low pressure metal button is selected as the operation button, with its own status indicator, which is safe and intuitive.
11. It can automatically compensate the temperature control effect caused by temperature or aging on the resistance value of silicon carbide rod, so as to avoid the inaccuracy and danger of manual adjustment.
