Vacuum tube furnaces are also a type of laboratory equipment, which may be unfamiliar to many. Next, the vacuum tube furnace manufacturer will specifically discuss the issues that should be paid attention to when using a vacuum tube furnace:

Tungsten tube furnace product features:

The design is compact, lightweight, and aesthetically pleasing, with reasonable craftsmanship. It features a monolithic furnace design for ease of use.

The furnace material is made using vacuum adsorption of polycrystalline mullite fiber, featuring lightweight, rapid heating, energy saving, time-efficient, heat shock resistance, and excellent insulation properties, capable of meeting various rapid sintering requirements. The open furnace structure with embedded heating elements ensures uniform furnace temperature and achieves over 60% energy saving.

3. The double-layered furnace shell structure, with advanced air insulation technology combined with thermal sensing technology, automatically activates the exhaust fan when the surface temperature of the furnace reaches 45°C, quickly cooling the surface to ensure the shell remains cool.

4. The enhanced gas circuit device features adjustable微量inlet and outlet gas flow, with pressure within the pipes clearly displayed by gauges for easy monitoring. Utilizing reliable multi-loop sealing technology, it improves the airtightness at both ends of the furnace tube. The quick-connect flange facilitates operation.

5. The gas conduit brackets support the gas conduit assembly, reducing the stress on the assembly itself and preventing damage to the furnace tubes. Heat dissipation exhaust fans are installed at the bottom of the brackets to cool the exposed parts of the tube, to prevent burns to the operators.

6. Equipped with an intelligent control system and a 50-program temperature control system, it can be programmed for various heating processes as needed. It features accurate PID control, fuzzy logic, self-tuning capabilities, and a function to restore parameter memory upon power-on.

Specific precautions when using a vacuum tube furnace are as follows:

1. Vacuum level and leak rate (relating to the furnace's sealing)

2. The time it takes to achieve vacuum (related to the quality of mechanical pumps and Roots pumps)

The fastest heating rate (often required by the process)

4. Cooling speed from the highest temperature to room temperature (production efficiency), with or without rapid cooling equipment

5. The maximum temperature achievable by the furnace and the maximum operating temperature of the furnace (note: these two are different).

6. Specifications and model numbers for vacuum gauges.

Can we utilize process gas, which relates to the usage requirements?

8. The material of the heating element, the wiring method between the heating element and the vacuum tube furnace power supply, and the insulation material. If it's graphite, it should be high-purity, preferably imported, with good insulation material, and the wiring structure should not easily lead to a short circuit.

9. The liquid collector is auxiliary but equally important. Most products contain some type of liquid, such as wax, so you'll want to note that the wax collector's cleaning port is easily accessible. If you use solidifying agents like paraffin, which are solid at room temperature, the wax collector can be heated to prevent clogs.
