Small Vacuum Melt Spinner Rapid Solidification Furnace for Amorphous and Nanocrystalline Ribbons

Product Overview

This advanced thermal processing system is a high-performance laboratory melt spinner designed specifically for the rapid solidification of metals, alloys, and intermetallic compounds. The primary function of this system is to transform molten materials into amorphous ribbons, nanocrystalline structures, or microcrystalline foils in a single, continuous process. By deploying high-frequency induction heating within a tightly controlled vacuum environment, the unit rapidly melts the target material and ejects it under pressure onto a high-speed rotating copper roller. The extreme thermal conductivity of the copper wheel, combined with its high linear velocity, forces the liquid alloy to cool at rates exceeding $10^5$ to $10^6$ Kelvins per second. This rapid cooling bypasses traditional thermodynamic crystallization pathways, yielding unique metastable phases and amorphous structures that exhibit superior mechanical, magnetic, and electrochemical properties.

Designed to meet the rigorous demands of advanced material science and industrial R&D laboratories, this equipment is extensively utilized across a broad range of sectors, including energy storage, microelectronics, aerospace, and high-frequency power distribution. It allows researchers to investigate new alloy compositions—such as soft magnetic alloys, high-entropy materials, metallic glasses, and lithium-based solid-state battery anodes—without the need for extensive raw material quantities. The system accommodates sample sizes starting as small as 5 grams, making it exceptionally cost-effective for screening expensive precious metals or rare-earth alloys before scaling up to larger production runs.

Engineered for reliable performance in demanding environments, this system features a heavy-duty, double-walled stainless steel chamber and highly durable vacuum components. Every critical system, from the high-speed copper roller to the induction coil assembly and the vacuum pumping stack, is manufactured to high tolerances. This robust construction ensures consistent thermal performance, long service life, and minimal downtime, even when conducting back-to-back testing runs at temperatures up to 2400°C. Researchers can trust the system to deliver repeatable ribbon profiles, uniform microstructures, and reliable experimental data for critical research projects.

Key Features

• Extreme Coolant Heat Transfer Rates: The system generates cooling rates ranging from $10^5$ to $10^6$ K/s, enabling the fabrication of high-quality amorphous ribbons and preventing crystalline nucleation to lock in disordered atomic structures.
• Broad Operating Temperature Profiles: Equipped with specialized high-frequency induction coils, the furnace can reach operating temperatures of 1700°C, 2000°C, or up to 2400°C, allowing researchers to melt refractory metals and high-melting-point alloys with absolute ease.
• High-Speed Copper Roller and Servo Control: The copper roller (200x40mm) is driven by a precision servo motor that allows infinitely variable speed control from 1 to 3000 r/min, translating to linear speeds up to 70 m/s for micro-adjustments in ribbon thickness.
• Magnetic Fluid Rotary Seal Technology: To maintain high vacuum integrity during high-speed rotation, the copper roller assembly uses a specialized magnetic fluid rotary seal, preventing atmospheric contamination and ensuring low leak rates.
• Precise Ribbon Geometry Control: Operators can easily adjust the thickness of the produced ribbons (from 20 to 60 micrometers) and the width (from 1 to 100 mm) by varying the nozzle-to-wheel gap, changing the gas ejection pressure, or adjusting the copper wheel's rotation speed.
• Flexible Environmental Controls: The system supports multiple melting environments, including high vacuum (10 Pa standard, upgradable to $10^{-5}$ Pa), partial pressures, or positive pressure inert gas protection to prevent the oxidation of highly reactive alloy components.
• Integrated Non-Contact Temperature Measurement: A high-precision infrared optical pyrometer is mounted directly to the chamber, providing real-time, non-contact temperature readings of the melt pool prior to ejection.
• Programmable PLC and Touch Screen Interface: An industrial-grade PLC control system with a user-friendly touch screen interface automates the entire casting sequence, allowing operators to monitor process parameters, adjust gas ejection settings, and log historical data.
• Double-Walled Water-Cooled Chamber: Built entirely from premium stainless steel, the vacuum chamber features a double-wall water-cooling jacket to ensure that the external shell temperature remains below 35°C for operator safety.
• Motorized Precision Lifting Mechanism: The crucible positioning and melting assembly utilizes a highly accurate motorized electric lift system to control the nozzle height relative to the copper roller, ensuring repeatability between subsequent casting runs.
