Hornos eléctricos de vacío

Vacuum furnaces are used for high-temperature vacuum and atmosphere-controlled heat treatment.

A vacuum furnace is a high-temperature device with an adjustable internal environment. It can operate under vacuum conditions or be purged with inert or reducing gases to meet the heating process requirements under different atmospheres.

As a common type of vacuum furnace, this type of furnace is widely used for processing materials sensitive to oxidation or requiring precise atmosphere control. In a vacuum or controlled atmosphere environment, oxidation and decarburization problems can be effectively reduced, thereby improving material properties and experimental stability.

We possess engineering expertise in heat treatment of 12 high-performance materials under combined vacuum and atmospheric stress conditions, and leverage our 2600°C composite heating platform to provide reliable assurance and precise control for every extreme application.

What is a Vacuum Furnace?

A vacuum furnace is a device capable of high-temperature heating in a vacuum or specific atmosphere, achieving precise temperature control through resistance heating or induction heating.

Its core feature is the ability to adjust the furnace atmosphere to meet the heat treatment requirements of different materials under varying conditions.

Main applications include:

• Vacuum sintering
• Metal annealing and heat treatment
• Materials synthesis and experimental research
• Ceramics and powder metallurgy processing

Vacuum Electric Furnaces Frequently Asked Questions (Preguntas frecuentes)

1. What is the difference between a vacuum furnace and a conventional furnace?

A vacuum furnace operates in an oxygen-free or controlled atmosphere, while a conventional furnace heats in air.

2. Why is atmosphere control necessary? What experiments is it suitable for?

Some materials are prone to oxidation or reaction at high temperatures. Atmosphere control protects material properties. It is suitable for experiments and heat treatment processes involving materials sensitive to oxidation or requiring specific atmospheric conditions.

3. What vacuum level can be achieved, and is the sealing reliable?

As a vacuum furnace, the furnace body features an integral sealed design, and the furnace door is equipped with a sealing ring and locking structure to ensure a high vacuum level (specific values ​​need to be confirmed based on the model).

4. Is operation complex?

Through gas path valves and the control system, one-button switching or program control of vacuum, gas filling, and atmosphere maintenance operations can be achieved.

5. What processes is it suitable for?

Suitable for oxidation-sensitive materials (such as titanium alloys and special ceramics) and processes that require treatment in a reducing atmosphere (such as metal reduction and sintering of tungsten and molybdenum materials).
