Split-Type 5KG Vacuum Induction Melting Furnace for Research and Development

Product Overview

This is a laboratory-scale vacuum induction melting furnace specifically engineered for research and development applications. With a 5-kilogram capacity, it strikes an optimal balance between small-batch processing and sufficient yield for prototype casting. The unique split-type horizontal door design simplifies loading and unloading, reducing downtime between experiments. This system provides a clean, high-vacuum environment essential for melting reactive and high-purity alloys.

Target users include materials science departments, metallurgy labs, and advanced manufacturing R&D teams. Common applications span from development of nickel-based superalloys and rare earth magnets to vacuum refining of precious metals and casting of specialty steels. The flexibility to use both quartz and graphite crucibles extends its compatibility to a wide range of metals, including those requiring ultra-high temperatures.

Reliability is assured through robust construction with an all-stainless steel chamber, precision IGBT power electronics, and industry-standard vacuum components. The two-stage vacuum system consistently achieves low outgassing and rapid pump-down, while the induction heating delivers repeatable thermal cycles. With proper maintenance, this furnace provides years of trouble-free operation, making it a trusted workhorse for demanding laboratory workflows.

Key Features

• Fully Stainless Steel Chamber: The vacuum chamber is fabricated from high-grade stainless steel, internally polished to a mirror finish to minimize outgassing and facilitate easy cleaning. The exterior receives a durable powder-coated finish, ensuring corrosion resistance and a professional appearance that lasts. This design not only extends the equipment’s lifespan but also maintains the purity of the melted materials by preventing contamination from rust or scale.
• Horizontal Split-Door Design: Unlike conventional top-loading furnaces, the horizontal split-door offers unrestricted access to the melting cavity, simplifying the loading of heavy crucibles and the removal of cast ingots. The door mechanism is counterbalanced for smooth operation, and the clear sight window allows real-time observation of the melt process. This ergonomic feature significantly reduces operator fatigue and improves productivity in experimental workflows.
• High-Temperature Capability: The standard configuration reaches 1700°C, suitable for most ferrous and non-ferrous alloys. By switching to a graphite crucible, temperatures exceeding 2100°C can be attained, enabling research on refractory metals and ultra-high-temperature ceramics. Temperature is precisely controlled via a PID loop, ensuring minimal overshoot and stable holding for critical melting sequences.
• IGBT Medium-Frequency Induction Heating: The IGBT-based power supply operates quietly and efficiently, converting electrical energy into intense magnetic fields that heat the charge directly. This method provides rapid heating rates and excellent energy utilization, while frequency optimization minimizes electromagnetic noise that could interfere with sensitive laboratory instruments. The power supply includes advanced diagnostics and protection circuits for safe operation.
• Two-Stage High-Vacuum System: Modular vacuum configurations let users choose the optimal pump combination for their budget and performance needs. The diffusion pump option delivers cost-effective high vacuum, while the turbomolecular pump variant provides oil-free, clean vacuum critical for oxygen-sensitive materials. A full-range vacuum gauge and automated sequencing ensure smooth evacuation and process repeatability.
• Versatile Crucible and Coil Options: The furnace comes with a set of quartz and graphite crucibles, accommodating a wide spectrum of materials. Interchangeable induction coils of different sizes allow optimization of the magnetic coupling for various charge weights and geometrics. This adaptability reduces turnaround time between experiments and expands the range of possible projects.
• Comprehensive Safety Features: Integrated interlocks, over-temperature protection, and water-cooling monitoring ensure safe operation for both personnel and equipment. The vacuum system includes automatic venting and pump isolation to prevent damage, providing peace of mind during unattended operation.
