Precision technology on vacuum high-temperature furnace

In the fields of semiconductor manufacturing, advanced ceramic R&D, and new energy material processing, vacuum high-temperature furnaces have become indispensable equipment for cutting-edge material innovation. Leveraging their oxygen-free environments, precise temperature control, and energy-efficient core advantages, these furnaces drive breakthroughs in high-performance materials. Building on decades of technical expertise, Shanghai Guanding Industrial Equipment has launched a next-generation vacuum high-temperature furnace solution. Centered on modular sealing architecture, intelligent thermal field regulation, and dynamic vacuum maintenance, this system delivers high-value technical support to research institutions and industrial enterprises.
Core Technical Features
The furnace employs a dual-layer inert gas circulation system and pressure-balancing technology. Its key components include:

1. Vacuum-Sealed Furnace Body

1. Constructed from seamless stainless steel, the furnace features multi-layer metal-ceramic composite seals paired with fluororubber gaskets and water-cooled partitions, ensuring long-term stability under vacuum conditions.

2. The double-axis linkage door (Dual axis linkage furnace door) integrates pressure self-balancing mechanisms and redundant mechanical locks to prevent accidental vacuum leaks caused by human error.
Translation Insight: "Linkage furnace door" is translated as "double-axis linkage door" to emphasize its mechanical sophistication. Standardized terms like "fluororubber" align with global material nomenclature, ensuring clarity for international engineers.

2. Composite Thermal Field System

1. The furnace lining uses zirconia fiber + nano-aerogel composite insulation, enhancing thermal efficiency while minimizing surface temperature fluctuations.

2. Heating elements combine molybdenum and tungsten wire arrays, with zonal temperature control achieving ±1°C precision. This supports multi-stage gradient heating programs for complex material processing.
Cultural Context: The use of zirconia fiber reflects China’s strategic focus on high-performance materials under its "Made in China 2025" initiative, aligning with global semiconductor manufacturing standards.

3. Intelligent Vacuum System

1. Integrates rotary vane pumps and molecular pumps for rapid evacuation, supported by vacuum gauges and pressure-rise rate sensors to maintain sub-10⁻³ Pa vacuum levels.

2. Equipped with argon/nitrogen circulation modules that continuously purge residual oxygen, preventing material oxidation and mitigating risks of combustible gas explosions.
