High Magnetic Field Tube Furnace with Triple Layer Vacuum Jacket and Non Magnetic SS316L Construction for Material Annealing

Product Overview

This high-precision thermal processing system is specifically engineered for material annealing applications within high-intensity magnetic environments. Utilizing specialized construction materials that exhibit nearly zero magnetic permeability, the equipment ensures that thermal treatments can be conducted inside superconducting high-field magnets without distorting magnetic flux or experiencing mechanical stress from magnetic attraction. This unit represents a critical tool for researchers focused on quantum materials, superconductivity, and advanced magnetism.

The system features a sophisticated triple-layer architectural design, integrating a heating element core, a dedicated sample chamber, and a vacuum/gas-insulated cooling jacket. This configuration allows for high-temperature operations while ensuring the external surface of the furnace remains at safe levels, preventing thermal interference with the surrounding superconducting magnet components. It is an essential solution for laboratory and industrial R&D facilities that require precise thermal control under extreme electromagnetic conditions.

Built for long-term reliability and consistency, the unit employs high-grade SS316L stainless steel for its structural components and advanced silicon carbide (SiC) heating elements. These choices reflect a commitment to durability and performance under demanding vacuum and high-temperature cycles. Procurement teams can trust this equipment to deliver repeatable results in sensitive experimental setups where standard tube furnaces would fail due to magnetic interference or thermal leakage.

Key Features

• Non-Magnetic SS316L Construction: The entire furnace body is fabricated from high-grade SS316L stainless steel, chosen for its negligible magnetic permeability. This allows the equipment to be placed directly into high-field magnets without causing field distortion or experiencing force displacement.
• Triple-Layer Thermal Management: The system utilizes a unique three-layer tube structure. An internal SiC filament provides the heat source, a secondary quartz layer houses the sample, and an outer gas-cooled jacket maintains the exterior wall temperature below 30ºC to protect external sensors and superconducting magnets.
• High-Efficiency Silicon Carbide Heating: Center-spiral SiC filaments provide rapid and uniform heating within the core zone. This heating technology is chosen for its stability at elevated temperatures and its ability to operate effectively within vacuum-jacketed environments.
• Precision PID Temperature Control: An advanced automatic PID controller features 30 programmable segments, allowing for complex ramp and soak profiles. The auto-tune function and ±1ºC accuracy ensure that delicate material transformations occur under strictly controlled conditions.
• Integrated Safety Protection: The unit includes built-in safeguards against thermocouple failure and overheating. These features are critical for long-duration annealing processes where equipment integrity and sample safety are paramount.
• Superior Vacuum Integrity: Designed to interface with high-vacuum systems, the equipment can achieve levels as low as 10^-5 Torr when paired with a molecular pump. The vacuum-sealed flanges ensure a contaminate-free environment for sensitive material processing.
• Active Cooling Jacket: The specialized 90mm O.D. outer layer functions as a gas-cooled thermal barrier. This design prevents heat from radiating into the magnet bore, which is essential for maintaining the cryogenic stability of superconducting systems.
• Flexible Gas Handling: Equipped standard with barbed hose fittings, the system can be upgraded with KF25 adapters or Swagelok fittings to accommodate high-purity gas delivery or higher throughput vacuum requirements.
