1650C High Temperature Atmosphere Controlled Box Furnace with 65L Chamber for Advanced Material Sintering and Industrial Heat Treatment

Product Overview

This high-temperature atmosphere-controlled box furnace represents the pinnacle of thermal processing technology for material science and industrial R&D. Engineered to facilitate precise sintering and heat treatment processes, this system offers a robust 65-liter chamber capable of reaching temperatures up to 1650ºC. Its dual-capability for operating under both inert gas and oxygen environments makes it a versatile asset for laboratories focused on the synthesis of advanced ceramics, metallurgical samples, and electronic components. The equipment is designed to bridge the gap between experimental research and pilot-scale production, providing the atmospheric purity and thermal precision required for sophisticated material development.

The equipment is built with a heavy-duty, vacuum-sealed steel case featuring an integrated water-cooling wall to maintain structural integrity and external safety while internal temperatures reach extreme levels. By integrating energy-saving 1800-grade alumina fiber insulation and high-performance heating elements, the unit ensures exceptional thermal efficiency and temperature uniformity across the entire 16x16x16 inch heating zone. This makes it an ideal solution for industries requiring rigorous, repeatable thermal cycles, including aerospace, semiconductor manufacturing, and advanced chemical research where consistency is the primary metric of success.

Reliability is at the core of this system's design. With a focus on long-term performance under demanding industrial conditions, the unit employs sophisticated monitoring systems and high-strength refractory materials. Procurement teams and researchers can rely on this furnace for critical applications where temperature accuracy and atmospheric integrity are non-negotiable. The inclusion of a comprehensive cooling system and a heavy-duty vacuum pump ensures that complex material transitions occur under perfectly controlled conditions, providing a turnkey solution for the most challenging thermal processing requirements.

Key Features

• Precision Atmospheric Control: The furnace is constructed with a vacuum-sealed steel case capable of maintaining a positive pressure up to 0.06MPa and a vacuum level down to -0.09MPa. This allows for strict control over internal environments, ensuring that sensitive materials are processed without contamination from ambient air.
• High-Grade MoSi2 Heating Elements: Utilizing twelve sets of 1800-grade Molybdenum Disilicide (MoSi2) coils, the system delivers consistent heating performance. These elements are strategically positioned on both sides of the chamber to ensure the highest level of temperature uniformity for large batches.
• Advanced Dual-Controller Safety Architecture: The equipment features two independent digital temperature controllers. The primary controller manages the 30-segment programmable heating curve with ±1ºC accuracy, while the secondary monitoring controller acts as a safety watchdog, activating an alarm and shutting down the system if the primary controller fails.
• Integrated Water-Cooling System: A high-efficiency water-cooling wall with dimensions of 470 x 410 x 550 mm surrounds the refractory muffle. Combined with a 16L/min recirculating water chiller, this system protects the vacuum seals and keeps the exterior of the furnace cool to the touch during peak operation.
• Energy-Efficient Thermal Insulation: The interior is lined with 1800-grade fibrous alumina insulation, which provides superior heat retention compared to traditional brick. This engineering choice reduces energy consumption and allows for rapid heating rates up to 10ºC per minute.
• Robust Load-Bearing Capability: The floor of the heated chamber is reinforced with a specialized Silicon Carbide (SiC) plate. This allows the furnace to accommodate heavy industrial loads or large ceramic crucibles up to a maximum weight of 100kg without compromising the refractory floor.
• Turnkey Gas and Vacuum Management: Every unit is equipped with a built-in gas float meter (12L/min), high-quality vacuum valves, and a KF40 vacuum port. The system includes a heavy-duty mechanical vacuum pump and all necessary connections, enabling immediate deployment for vacuum or inert gas processing.
• Structural Durability: The refractory muffle is built to withstand repeated thermal expansion and contraction, ensuring a long service life even when subjected to continuous high-temperature cycles between 800ºC and 1600ºC.
