Touchscreen Non Consumable Vacuum Arc Melting Furnace for High Entropy Alloys and Refractory Metals Laboratory Arc Melter

Product Overview

This system is a state-of-the-art thermal processing solution engineered specifically for high-purity metallurgical synthesis, alloy development, and advanced material research. By utilizing a non-consumable tungsten electrode to strike a high-energy electric arc against raw materials, this equipment delivers the localized temperatures required to melt refractory metals and complex alloys. The melting process occurs within a hermetically sealed, water-cooled vacuum chamber, ensuring that oxygen-sensitive or reactive materials are synthesized without atmospheric contamination. Designed with modern digital controls, this unit bridges the gap between manual laboratory melting and automated, repeatable industrial R&D processes.

Primarily utilized in material science laboratories, aerospace engineering departments, nuclear research centers, and advanced metallurgical institutes, the equipment excels at synthesizing high-entropy alloys (HEAs), titanium alloys, and refractory materials such as niobium, tantalum, and tungsten. The system is engineered to handle small-scale experimental melts and pilot batches, offering a critical platform for developing new metal matrix composites and amorphous alloys. Its compact footprint combined with industrial-strength components makes it a versatile asset for both academic research and corporate research and development centers.

Operating under extreme thermal gradients and deep vacuum environments requires absolute mechanical integrity. This unit is built to withstand continuous thermal cycling, featuring a robust, water-jacketed stainless steel chamber and highly efficient water-cooled copper hearths. With integrated safety interlocks, automated valve control, and grid-friendly power regulation, this system provides operators with the reliability and operational consistency necessary to achieve reproducible experimental results. Every component, from the pneumatic valves to the electrode positioners, is chosen to ensure long-term durability and uptime in demanding research environments.

Key Features

• Intelligent Touchscreen Control Interface: The unit features an integrated PLC paired with a high-resolution color touchscreen interface, enabling researchers to monitor and control vacuum levels, arc current, voltage, and gas purging cycles from a centralized dashboard. Real-time data logging and recipe storage ensure that exact experimental parameters can be recorded and replicated for future trials.
• Water-Cooled Non-Consumable Tungsten Electrode: Designed for high-current operations, the heavy-duty tungsten electrode assembly is thoroughly water-cooled to prevent erosion and thermal degradation. This configuration allows for stable, continuous arc ignition and maintains the purity of the melt pool by preventing electrode material from contaminating the alloy.
• Integrated Electromagnetic Stirring Module: To overcome compositional segregation during solidification, the system incorporates an adjustable electromagnetic stirring (EMS) module. The Lorentz force induced in the melt pool promotes convective flow, yielding uniform element distribution and refined grain structures in complex multi-component alloys.
• Double-Layered Welded Vacuum Chamber: The vacuum chamber is fabricated using industrial-grade SUS304 stainless steel with double-sided welding on the internal layers and single-sided welding on the external surfaces. This rigorous structural design eliminates micro-leakage pathways, allowing the system to achieve and maintain clean high-vacuum levels consistently.
• Customizable Water-Cooled Copper Crucible: Equipped with a highly conductive, water-cooled copper hearth featuring multiple melting pockets. The multi-cavity design allows researchers to melt, flip, and re-melt samples or run multiple composition variations in a single vacuum cycle without opening the chamber.
• Grid-Safe Power Source Integration: Utilizing an advanced inverter power supply, the system regulates electrical output smoothly without causing power surges or harmonic feedback to the local laboratory electrical grid. This protective design ensures that nearby analytical instruments and computers operate without interference during high-power arc strikes.
• Suction and Tilt Casting Upgrade Options: The system can be configured with integrated suction casting or tilt casting modules, allowing the molten alloy to be immediately cast into copper molds. This capability enables the rapid production of cylindrical rod specimens, sheet samples, or near-net-shape specimens directly under vacuum.
• Comprehensive Multi-Point Safety Interlocks: Engineered with an array of safety sensors, the system continuously monitors cooling water pressure, chamber temperature, vacuum thresholds, and electrical current limits. Any deviation from safe operating limits triggers an automated shutdown of the power supply and seals the gas lines to protect the operator and the hardware.
