High Corrosion Vacuum Melting Furnace

Product Overview

This high-corrosion vacuum melting furnace is a purpose-built system for the melting, sintering, and purification of highly corrosive fluoride-based materials. Its vertical chamber, constructed from corrosion-resistant stainless steel with an internal anti-corrosion coating, withstands aggressive chemical environments that standard equipment cannot handle. Operating at up to 900°C with a high vacuum of 1 Pa, the furnace provides an ultra-clean processing environment essential for high-purity material synthesis.

Designed for pilot-scale production and research, this unit is ideal for university laboratories, materials science institutes, and industrial R&D centers. Typical applications include processing fluoride compounds for optics, nuclear technology, and battery research. Its versatile atmosphere control with inert gas backfill broadens its utility across multiple corrosive-material workflows.

With a double-layer water-cooled jacket and comprehensive safety interlocks, this system ensures stable, long-term operation. Induction heating delivers rapid, uniform melting with built-in electromagnetic stirring for compositional homogeneity. The integrated overpressure protection and alarm functions guarantee operator safety, making it a reliable choice for demanding research programs.

Key Features

• Superior Corrosion Resistance: The chamber and all internal components are made from high-grade stainless steel with a proprietary anti-corrosion spray coating. This dual protection effectively resists fluorine gas, hydrofluoric acid vapor, and other reactive halogens, ensuring a long service life.
• High Vacuum Performance: A cold-state ultimate vacuum of 1 Pa is achieved through a two-stage pumping system, removing moisture, oxygen, and contaminants. The pressure rise rate of ≤4 Pa/h indicates excellent sealing integrity and minimal outgassing, maintaining purity during extended melts.
• Precise Temperature Control: Advanced PID-controlled induction heating allows rapid, uniform heating up to 900°C with minimal overshoot. The electromagnetic stirring effect enhances mixing, yielding homogeneous melts and consistent batch quality.
• Integrated Safety Features: Standard protections include water failure detection, overcurrent protection, furnace over-temperature alarm, and water over-temperature alarm. An overpressure explosion-proof system automatically vents the chamber if internal pressure exceeds safe limits.
• Effective Thermal Management: The double-layer water-cooled jacket maintains a safe exterior surface temperature, protecting operators and adjacent equipment. This efficient cooling also stabilizes vacuum seals and prolongs chamber life.
• User-Friendly Operation: The intuitive control interface allows easy programming of temperature ramps, vacuum sequences, and gas backfill operations. Real-time display of process variables enables precise monitoring and data logging.
• Compact and Rugged Design: The vertical, top-loading configuration saves floor space while providing convenient access for sample loading and sampling. Heavy-duty construction reliably withstands frequent thermal cycling.
• Flexible Capacity: The standard furnace accommodates fluoride charges from 200 g to 500 g, suitable for both small-scale experiments and pilot production. Custom crucible options are available for different batch sizes.
• Inert Gas Compatibility: A built-in gas inlet system allows backfilling with high-purity argon or nitrogen up to 0.03 MPa, enabling processing under controlled atmospheres to suppress evaporation or prevent unwanted reactions.
• Low Maintenance Requirements: Designed for ease of service, the furnace includes accessible internal components and a simple vacuum pump arrangement, minimizing downtime and reducing the total cost of ownership.
