1700C High Temperature Quenching Tube Furnace with 60mm Alumina Tube and Automatic Electromagnet Release System

Product Overview

This high-temperature thermal processing system is an advanced laboratory-grade solution designed specifically for quenching and material phase studies. By integrating a vertical tube furnace with a precision-controlled sample release mechanism, this equipment allows researchers to heat materials to temperatures as high as 1700°C before immediately plunging them into a quenching medium. This rapid cooling capability is essential for freezing high-temperature microstructures, enabling the detailed study of metastable states and phase transformations that would otherwise be lost during slower cooling processes.

Engineered for use in demanding material science and industrial R&D environments, the system provides a controlled atmosphere or vacuum environment to protect sensitive samples from oxidation or contamination. The vertical orientation is optimized for gravity-assisted quenching, ensuring a seamless transition from the heating zone to the quenching tank located directly beneath the furnace core. This unit is particularly effective for metallurgy, ceramic engineering, and the development of high-performance alloys where thermal history significantly dictates the final mechanical and chemical properties of the material.

Constructed with a focus on long-term operational reliability, the equipment utilizes premium 1800-grade molybdenum disilicide (MoSi2) heating elements and high-purity fibrous alumina insulation. The double-layer steel casing features integrated air cooling, maintaining a safe and stable external surface temperature even during prolonged high-heat cycles. This robust engineering ensures that the system delivers consistent, repeatable results, providing procurement teams and lead investigators with the confidence that their thermal processing workflows will remain uninterrupted and highly precise.

Key Features

• Precision 1700°C Thermal Management: The system utilizes four U-shaped 1800-grade MoSi2 heating elements to reach a maximum operating temperature of 1700°C, with a reliable continuous operating range of 800°C to 1600°C for long-term stability.
• Automated Electromagnet Sample Release: A fully integrated electromagnetic hanger system allows for the instantaneous release of samples into the quenching tank. By simply pressing a release button, the electromagnet deactivates, allowing the sample to fall vertically through a large gate valve without manual intervention or thermal loss.
• High-Purity Alumina Processing Tube: The equipment is outfitted with a 99% high-purity Al2O3 ceramic tube (OD: 60mm, ID: 54mm) that offers exceptional resistance to thermal shock and chemical corrosion at extreme temperatures, ensuring a clean processing environment.
• Integrated Quenching Infrastructure: A dedicated stainless steel quenching tank is positioned at the base of the furnace, connected via a 4-inch manually operated gate valve and CF-100 adaptor to maintain vacuum or atmosphere integrity until the moment of release.
• Advanced PID Control Logic: The standard temperature controller features 30 programmable segments for ramping, cooling, and dwelling, utilizing an auto-tune function to maintain temperature accuracy within ±1°C, minimizing thermal overshoot.
• Optimized Heating Zone Architecture: With a 130mm heating zone and a 60mm constant temperature zone (within ±5°C), the furnace ensures uniform heat distribution across the sample surface, which is critical for achieving consistent material properties across different batches.
• Versatile Atmosphere and Vacuum Control: The vacuum-sealed flanges and high-quality valves allow for operations under 50 mTorr vacuum or pressurized inert gas environments (up to 3 PSI), providing total control over the chemical environment surrounding the sample.
• Safety-First Engineering: The unit includes built-in over-temperature and thermocouple failure alarms, and the double-layer casing design minimizes radiant heat to the laboratory environment, prioritizing operator safety and equipment longevity.
• Flexible Sample Handling: The electromagnet system supports a sample hanging wire up to 500g, while the design accommodates samples up to 50mm in diameter and 65mm in length, making it suitable for a wide variety of experimental geometries.
