Motorized Swing Vacuum Arc Melting Furnace for Active and Refractory Alloys

Product Overview

This vacuum electric arc melting system represents the pinnacle of high-temperature thermal processing technology designed for advanced materials research, metallurgy, and industrial R&D. Engineered specifically to process active, reactive, and refractory metal alloys, this system leverages a non-consumable tungsten electrode and a water-cooled copper hearth. The unit achieves localized temperatures exceeding 3500°C without introducing contaminants or structural impurities into the melt. By maintaining a highly controlled, high-vacuum atmosphere, the system prevents oxidation, nitridation, and other ambient reactions, making it an indispensable tool for synthesizing high-purity alloys, intermetallics, and novel materials.

Targeted primarily at research institutions, aerospace engineering laboratories, nuclear research facilities, and specialty metal producers, the equipment supports critical metallurgical processes including suction casting, electromagnetic stirring, and custom welding operations. Whether you are developing lightweight titanium-based alloys for aerospace applications, analyzing refractory niobium or tantalum systems, or experimenting with complex high-entropy alloys, this system provides the thermal precision and atmosphere integrity required to achieve consistent, repeatable results.

Designed for demanding environments, this furnace features a robust double-walled stainless steel chamber, an integrated closed-loop water chiller, and comprehensive safety monitoring loops. This structural design ensures safe, continuous operation over multiple high-temperature melting cycles. The thermal management system is optimized to withstand extreme thermal fluctuations, ensuring long-term operational durability and minimizing maintenance intervals, which guarantees that research programs proceed without unexpected interruptions.

Key Features

• Motorized 360-Degree Swing Electrode: The system integrates a motorized swing copper electrode assembly that enables smooth 360-degree positioning across the melting hearth. This motorized control removes the physical strain and positioning errors associated with traditional manual handle adjustments, allowing operators to manipulate the arc path precisely. This smooth, motorized positioning reduces the risk of electrode-crucible contact and guarantees consistent arc distance management.
• Ultra-High Temperature Melting Power: Powered by a dedicated, high-stability arc melting power supply, this system generates localized temperatures exceeding 3500°C. This allows researchers to rapidly melt and homogenize refractory metals such as tungsten, tantalum, and molybdenum under high vacuum or inert gas backfill conditions while maintaining a highly stable arc discharge.
• High-Vacuum Preservation Chamber: The double-walled stainless steel chamber is engineered to achieve a baseline ultimate vacuum of 6.7 x 10^-4 Pa (with capabilities reaching 5.0 x 10^-4 Pa and higher using premium pump configurations). This level of vacuum integrity protects active metals like titanium, zirconium, and rare-earth alloys from ambient contamination during high-temperature phases.
• Material Charging Versatility: This system accommodates a wide variety of feedstock geometries, allowing researchers to load powders, wires, turnings, chips, granules, strips, and rings directly into the water-cooled copper hearth. This versatile capability facilitates the synthesis of custom alloy compositions directly from elemental raw materials or the recycling of scrap specimens.
• In-Situ Material Turnover Device: To overcome the challenge of non-uniform, single-sided melting, the chamber incorporates an internal flipping manipulator. This device allows operators to rotate solidified ingots 180 degrees without breaking the vacuum or cooling down the entire system, ensuring chemical and structural homogeneity.
• Intuitive Touchscreen PLC Controller: The furnace is operated through a centralized PLC-based human-machine interface (HMI). The system displays real-time operational parameters, including chamber pressure, electrode current, voltage, and water temperature, enabling precise process programming and safety interlock monitoring.
• Advanced Eye and Thermal Protection: An oversized viewing port with radiation-shielding filtered glass is integrated into the side-opening door, protecting operators from intense UV and IR emissions during arc execution. An internal sliding shutter prevents metal vapors from depositing on the viewport glass.
• Turnkey Closed-Loop Cooling System: The system comes equipped with a pre-configured closed-loop water chiller, providing immediate, plug-and-play installation. This chiller maintains safe operating temperatures for the vacuum chamber walls and copper electrodes during high-power cycles.
