Stepped Vacuum Induction Distillation Furnace for Metal Melting and Distillation Under Vacuum

Product Overview

This stepped vacuum induction distillation furnace is a specialized high-temperature system engineered for melting and distilling metal materials under a clean vacuum or precisely controlled protective atmosphere. By integrating induction heating with a vertical layered condensation structure, it enables efficient separation and collection of volatile constituents, making it an essential tool for high-purity metal processing.

Universities, research institutes, and production enterprises rely on this unit for advanced material development, alloy preparation, and the recovery of rare or high-value metals. Its ability to maintain stable thermal gradients and ultra-low vacuum levels makes it ideal for both fundamental research and small-scale pilot production.

Built with robust components and a precision control system, the furnace delivers consistent, repeatable results even under demanding high-temperature, high-vacuum conditions. Its durable construction and user-focused design ensure long service life with minimal maintenance, giving operators confidence in every cycle.

Key Features

• Precision Temperature Control: An infrared monitoring system tracks crucible temperatures up to 1800°C, while the PLC-based PID controller maintains stable setpoints for precise melting and distillation profiles.
• High Vacuum Performance: A cold ultimate vacuum of ≤6.7×10⁻³ Pa and a low pressure rise rate of ≤4 Pa/h ensure an ultraclean environment, minimizing contamination and oxidation for high-purity output.
• Layered Condensation Design: The vertical stepped condensation collector efficiently traps distilled materials, utilizing thermal gradients to separate components with differing volatilities.
• Protective Atmosphere Compatibility: The system can operate with inert gases such as nitrogen or argon at pressures up to 0.03 MPa, further broadening the range of processable materials.
• User-Friendly Control Interface: An operation simulation screen coupled with a PLC provides intuitive control, real-time data display, and programmable cycles for enhanced repeatability and ease of use.
• Versatile Crucible Capacity: With a 500–1000 g crucible (based on steel density) and a φ70×90 mm crucible size, it accommodates a wide range of sample quantities for R&D and pilot-scale trials.
• Compact Vertical Construction: The vertical configuration and chamber size of approximately φ400×600 mm save valuable laboratory space while ensuring efficient thermal management and easy access.
