Vacuum Box Furnace

Vacuum Box Furnace

A vacuum box furnace is used for heat treatment, sintering, and annealing processes under vacuum or protected atmosphere conditions. It is suitable for laboratory and industrial pilot applications. It is ideal for high-temperature processing processes requiring specific atmosphere and cleanliness.

The box furnace structure provides a large furnace chamber, facilitating the placement of workpieces or samples of varying sizes. During operation, the furnace environment can be controlled by evacuation or the introduction of inert or reducing gases, thereby reducing oxidation and improving material processing quality.

Product Features (Vacuum Box Furnace)

1. Large-capacity furnace chamber

This series of vacuum box furnaces features a large-capacity furnace chamber design, combined with a clean, integrated vacuum-gas structure to avoid cross-contamination and meet high-purity heat treatment requirements.

2. Flexible switching between vacuum and atmosphere protection

It can be evacuated and inert gases (nitrogen, argon) or reducing gases (hydrogen) can be introduced to achieve processes such as vacuum sintering, atmosphere-protected annealing, and degassing. Excellent sealing performance ensures a stable atmosphere inside the furnace, effectively preventing material oxidation.

3. Maximum temperature of 1800℃, multi-temperature zone options supported

Temperature control can reach up to 1800℃, supporting independent temperature control configurations for multiple zones. Depending on process requirements, high-temperature alloy resistance wire, silicon carbide rod, or silicon molybdenum rod heating elements can be selected to adapt to the sintering and heat treatment requirements of different materials.

4. Flexible gas inlet system

Equipped with an adjustable gas inlet system, supporting switching between multiple atmospheres such as nitrogen, argon, and hydrogen. Gas flow rate can be precisely controlled to meet the stringent requirements of different processes regarding atmosphere composition and flow rate.

5. High-quality furnace lining, energy-saving and heat-insulating

The furnace lining is made of vacuum-formed high-purity alumina lightweight material, which has low heat storage, is resistant to rapid heating and cooling, and has excellent heat insulation performance. The furnace body has a double-layer air-cooled structure, with an outer shell temperature ≤45℃, ensuring safe and comfortable operation.
