Fully automatic loading and unloading vacuum tube furnace

Description：

Polycrystalline ceramic fiber is used, which does not drop powder, has good thermal insulation performance, high reflectivity, balanced temperature field, and strong resistance to thermal expansion and contraction....

Introduction:
The KJ-T1200-50XY is a vacuum tube furnace with an integrated fully automatic loading and unloading system, designed specifically for heat treatment processes requiring high efficiency, repeatability, and a vacuum environment. The equipment employs a pneumatically controlled flange movement mechanism. One flange is fixedly connected to the vacuum system, while the other flange is mounted on a guide rail. A pneumatic device automatically presses and seals the flange, enabling rapid and stable opening and closing of the furnace tubes and sample loading and unloading, significantly reducing operational burden and improving process consistency.

Application Areas

This equipment is particularly suitable for laboratories and small-batch production scenarios requiring frequent sample loading, vacuum environments, and automated operation, specifically including:

1. Vacuum Heat Treatment
Metallic Materials: Annealing, solution treatment, and stress relief of stainless steel, titanium alloys, and cemented carbide under vacuum conditions.

Powder Metallurgy: Vacuum sintering of metal powders or compacts to prevent oxidation.

Magnetic Materials: Vacuum heat treatment of permanent magnet materials such as neodymium iron boron.

2. Material Synthesis and Preparation
Nanomaterials: Synthesis of carbon nanotubes, nano-metal particles, and quantum dots under vacuum or a protective atmosphere.

Semiconductor Materials: Vacuum annealing and alloying of silicon wafers and compound semiconductors.

Ceramic Materials: Vacuum pre-sintering or sintering of advanced ceramics (Al₂O₃, ZrO₂, Si₃N₄).

3. New Energy Materials

Lithium-ion Batteries: Vacuum sintering of cathode materials (lithium iron phosphate, ternary lithium-ion); carbon coating heat treatment of anode materials (silicon-carbon, tin-based).

Fuel Cells: Vacuum calcination of electrolyte membranes; pyrolysis of catalyst precursors.

4. Chemical Engineering and Environment

Catalyst Activation: Reduction and calcination of supported catalysts under vacuum or atmospheric conditions.

Materials Pyrolysis: Pyrolysis of organic precursors and biomass under vacuum conditions to prepare carbon materials.

5. Scientific Research and Teaching
As a highly automated general-purpose tube furnace, it is used in universities and research institutions for new material development, process optimization, and student experiments, especially suitable for research projects requiring multiple batches and repetitive operations.
