Vacuum Induction Melting Furnace for Lithium Metal and Reactive Alloys

Product Overview

This system represents a specialized thermal processing solution designed for the melting, alloying, and casting of highly reactive metals under ultra-low pressure or high-purity inert gas environments. Engineered primarily to handle metallic lithium and other volatile alloys, the equipment utilizes advanced induction heating to deliver rapid heat-up rates and superior thermal efficiency. By isolating materials within a hermetically sealed vacuum chamber, it prevents reaction with atmospheric oxygen, nitrogen, and moisture, thereby maintaining the chemical purity and structural integrity of the processed samples.

Optimized for high-temperature laboratory research and industrial R&D, this unit is widely utilized in solid-state battery development, aerospace metallurgy, rare-earth magnet synthesis, and advanced nuclear materials research. The integration of high-precision temperature tracking and automated atmospheric controls enables material scientists to conduct repeatable melting cycles, casting operations, and heat treatments. Its compact footprint and integrated structural design make it ideal for facilities requiring pilot-scale capability without sacrificing laboratory floor space.

Built to withstand rigorous thermal cycles and continuous duty, the equipment relies on robust construction materials and premium industrial components. The vacuum chamber is fabricated from high-grade stainless steel with precision welded seams, ensuring minimal leak rates and long-term durability. Operators can proceed with confidence, knowing that the integrated safety interlock network, water-cooling monitors, and automated pressure relief systems protect both the operator and the system components during every high-temperature run.

Key Features

• Advanced Induction Heating Efficiency: High-frequency induction coils couple directly with the crucible assembly to deliver rapid thermal transfer, enabling full melting and sample testing cycles to be completed in under 10 minutes.
• Ultra-High Vacuum Performance: Equipped with a high-capacity turbomolecular pump system backed by a mechanical pump, achieving an ultimate cold vacuum level of 6.67 × 10^-4 Pa to eliminate atmospheric contaminants.
• Non-Contact Infrared Pyrometry: An integrated optical pyrometer monitors the melt temperature continuously without contact, preventing sensor degradation and providing accurate PID feedback across the entire operating range.
• Intelligent PLC and Touchscreen Automation: The human-machine interface allows operators to program multi-step heating recipes, control gas purge cycles, monitor system state visual graphics, and log historical process data.
• Dual-Gas Inert Protection Management: Designed to support regulated backfilling of high-purity nitrogen or argon up to 0.03 MPa, allowing controlled positive-pressure processing to suppress metal vaporization.
• Double-Wall Water-Cooled Chamber: The heavy-duty stainless steel vacuum chamber features built-in water-cooling channels to ensure the exterior remains cool to the touch and O-ring seals are protected from thermal stress.
• Comprehensive Multi-Tiered Safety Interlocks: Automatic protection loops monitor water flow rate, chamber pressure, and induction coil power, executing immediate shutdown sequences if operating parameters deviate from safe thresholds.
• Precision Mechanical Casting Integration: Ergonomically positioned pouring controls enable smooth, controlled crucible tilting under full vacuum or inert gas conditions, yielding consistent ingot molds.
