High Temperature Vertical Three Zone Powder Spheroidizing Furnace for Advanced Material Synthesis and Industrial Thermal Processing

Product Overview

This high-temperature vertical processing system offers a precision-engineered solution for material scientists and industrial researchers focused on powder spheroidizing and morphology optimization. By integrating a three-zone furnace with a speed-adjustable vibration feeder and an efficient water-cooled collection mechanism, the equipment enables the continuous processing of fine powders under controlled atmospheric or vacuum conditions. It is specifically designed to meet the rigorous demands of modern material synthesis, where particle shape consistency is paramount for the performance of high-tech materials.

Primarily utilized in the development of advanced magnetic materials, metal powders for additive manufacturing, and high-purity ceramics, this unit provides a versatile platform for thermal processing up to 1700°C. The vertical orientation utilizes gravity as a dynamic force, allowing powders to pass through precisely controlled thermal gradients during descent. This flight path is critical for achieving uniform spheroidization through surface tension-driven reshaping, making this system a cornerstone for R&D labs and industrial pilot lines seeking professional-grade results.

Built with industrial-grade components and a heavy-duty double-shell frame, the equipment ensures long-term reliability and repeatable performance under demanding conditions. The air-cooling system protects internal components and maintains a safe exterior temperature even during prolonged high-heat cycles. Users can rely on this robust thermal system for critical processes where temperature stability and mechanical durability are essential for operational success in material science and industrial metallurgy.

Key Features

• Independent Triple-Zone Thermal Control: The heating chamber is divided into three separate segments, each 400mm in length, allowing operators to create specific temperature gradients or a long, uniform isothermal zone to accommodate complex powder processing requirements.
• Precision Vibration Feeding Mechanism: Featuring a 5L stainless steel storage chamber, the speed-adjustable feeder ensures a constant and non-clumping flow of powder materials into the furnace tube at rates between 20ml and 90ml per minute.
• Rapid Water-Cooled Quenching System: A specialized collection tank at the base of the vertical tube enables immediate thermal arrest, preserving the spherical morphology of the particles developed during the high-temperature flight phase.
• Advanced 30-Segment PID Regulation: The control system utilizes sophisticated proportional-integral-derivative algorithms with 30 programmable segments for precise ramping, dwelling, and cooling cycles, maintaining thermal accuracy within ±1°C.
• High-Performance Atmosphere and Vacuum Versatility: Equipped with KF25 vacuum flanges and a sealed chamber design, the system supports sintering in inert atmospheres or under high vacuum (up to 10-4 Torr with optional molecular pumps) to prevent oxidation of sensitive materials.
• Industrial-Grade Type B Thermocouples: High-purity Type B sensors provide accurate feedback for high-temperature operations, ensuring that the continuous working temperature of 1600°C is monitored with the highest levels of stability and sensitivity.
• Enhanced Safety and Cooling Architecture: The double-shell structure includes an integrated fan-assisted air cooling system that reduces the exterior casing temperature, while built-in over-temperature and thermocouple failure alarms protect the hardware and the environment.
• Scalable Digital Communication: The unit is equipped with a standard DB9 PC communication port, allowing for optional Labview-based software integration for recipe management, data logging, and remote monitoring via a desktop or laptop interface.
