Introduction
Laboratory furnace (vacuum furnace) is a vacuum resistance furnace that uses graphite as the heating element. It is mainly applied for high-temperature sintering of ceramics, hard alloys, composite materials, etc., under vacuum or protective atmospheres. It can also be used for high-temperature heat treatment of metal materials in high vacuum conditions or degassing treatment of precious metal materials.
Technical Features
- Horizontal, side-opening design: Easy loading and unloading of materials; comfortable operation.
- Fast heating: Heating rate of 5°C/min (≤1600°C) and 1°C/min (>1600°C).
- Thermal field simulation design: The heating chamber's thermal field is simulated with thermal state calculations, optimizing the arrangement of heating elements and insulation layers for excellent temperature uniformity and insulation performance.
- Multi-zone control: Multiple reserved temperature measurement holes, with full temperature monitoring from 0 to 2800°C.
- Temperature uniformity: ≤±5°C (tested after temperature stabilization in the insulation zone).
- Fast cooling: An optional rapid cooling system ensures efficient operation.
- High stability: Long-term stable and reliable operation with low failure rates.
- Excellent safety: Equipped with IGBT + PLC + PID temperature control system, ensuring safety and reliability.
- Strong expandability: Suitable for sintering, annealing, degreasing, and degassing processes.
Technical Features
- Thermal field/furnace chamber: Graphite furnace chamber.
- Heating elements: Graphite.
- Maximum temperature/working temperature: 3000°C/≤2800°C.
- Vacuum level: High vacuum, low vacuum optional.

Application Fields
- This is a batch operation system suitable for sintering processes under high temperature and high vacuum conditions, particularly for materials such as graphite electrodes and ceramics. It can also be used for sintering under protective atmospheres or for purification of carbon materials. Other applications include the alloy and metallurgy industries, such as sintering of hard alloys, refractory materials, and ultra-high temperature materials.
- Specific applications include carbon/carbon brake discs, carbon-carbon plates, hot-press molds, high-temperature heating elements/fasteners, thermal field materials, graphite products, carbon paper, carbon cloth, graphene, and carbon nanotubes.
