Miniature Vacuum Electric Arc Melting Furnace for Lab Scale Active Metal Alloy Smelting

Product Overview

This high-performance thermal processing system is a state-of-the-art miniature vacuum electric arc melting furnace engineered for laboratory-scale fabrication and R&D. Designed to handle reactive, refractory, and active metals, the equipment delivers intense localized heating to rapidly melt alloy samples in a controlled atmosphere or high-vacuum state. By utilizing a clean, non-consumable tungsten electrode and a water-cooled copper hearth, the system ensures zero contamination of high-purity materials, making it an indispensable asset for advanced materials science and metallurgical research.

The system is highly optimized for academic research, aerospace materials engineering, nuclear power R&D, and industrial laboratories focused on synthesizing advanced alloys, superalloys, and composite materials. Its versatile design accommodates various raw material geometries, allowing operators to melt powders, wires, turnings, granules, and sheets with identical efficiency. With its compact footprint and self-contained cooling layout, this unit integrates seamlessly into modern laboratory spaces without requiring complex facility modifications.

Built to meet the rigorous demands of continuous industrial and laboratory testing, the system provides long-term reliability under extreme thermal gradients and high-vacuum conditions. The chamber construction, electrode design, and electrical insulation are engineered to perform consistently through repetitive melting cycles. Researchers can operate with absolute confidence in the repeatability of their experimental melts, supported by robust safety systems and precise process monitoring controls.

Key Features

• Extreme Operating Temperatures: The furnace generates stable electric arcs capable of exceeding 3500°C, enabling clean and rapid melting of refractory metals such as titanium, zirconium, niobium, and tantalum.
• High-Vacuum Environmental Integrity: Equipped with a high-efficiency vacuum pumping configuration, the unit achieves an ultimate vacuum pressure of 5 x 10^-4 Pa or higher, preventing oxidation and gas absorption in highly reactive metal melts.
• Flexible 360-Degree Movable Electrode: The water-cooled copper electrode offers full 360-degree range of motion, allowing operators to manipulate the arc manually to target specific zones of the charge or sweep the arc for uniform heat distribution.
• Integrated Sample Overturning Mechanism: The copper hearth features an innovative tilting and overturning mechanism that enables operators to flip sample buttons under vacuum, ensuring uniform melting on both sides without breaking the protective atmosphere.
• Double-Walled Water-Cooled Chamber: The vacuum chamber is constructed from heavy-duty, double-walled stainless steel with an integrated cooling jacket, maintaining a safe outer shell temperature and preventing thermal deformation during prolonged runs.
• Intuitive Mimic Control Panel: A user-friendly control interface displays real-time system status, vacuum levels, electrode power parameters, and coolant flow rates, ensuring straightforward operation and minimal learning curves for research personnel.
• Dual-Layered Eye-Protection Viewport: The large-diameter observation window is fitted with a specialized optical filter glass that blocks harmful ultraviolet and infrared radiation, allowing safe, real-time visualization of the arc and melt pool.
• Turnkey Cooling System Integration: The unit comes standard with a pre-configured, closed-loop water chiller that connects directly to the electrode and hearth, facilitating fast installation and immediate operation upon delivery.
• Multi-Form Feedstock Adaptability: Designed to process varied charge configurations, the crucible accommodates fine powders, wire segments, metal shavings, granular pieces, strips, and ring-shaped inputs without compromising melt efficiency.
• Multi-Functional Process Configuration: Beyond basic melting, the furnace supports configurations for suction casting, tube welding, and localized heat treatments, providing outstanding versatility for diverse alloy development projects.
