Sealed Rotary Vacuum Furnaces for Complex High-Efficiency Powder Processing
GWDLTHERMO vacuum rotary furnaces are specifically designed to support thermal processing of ultra-high-purity powders up to 5N grade (99.999%), such as electronic-grade quartz, rare earths, and semiconductor materials. The sealed rotary tube design ensures exceptional atmosphere integrity, minimizing contamination and reducing the loss of high-cost gases like hydrogen or HCl during chlorination or reduction processes.
With an intelligent integrated control system, the furnace synchronizes drum rotation, temperature zoning, gas flow, and feeding/discharge, ensuring stable reaction conditions and optimized throughput.
We specialize in complex, process-driven customizations:
1050°C large intermittent rotary kiln with liftable furnace tube for batch processing of powders, ceramics, and advanced materials. Features PLC automation, atmosphere control, and high thermal uniformity for precision calcination and sintering.
GWL-1000SSR 1000℃ multi-zone rotary kiln for silica slurry drying and impurity calcination. Continuous high-volume production, fully automated operation, integrated off-gas purification, and waste heat recovery for efficiency and environmental performance.
Sealed quartz tube rotary furnace: high-purity quartz glass or corundum 99 ceramic tubes, integrating precise temp control (±1℃), multi-atmosphere treatment, intelligent rotation. Designed for high-end powder heat treatment. Excellent sealing, ideal for research institutes/enterprises in material R&D and production.
Tilting and Rotating Vacuum Atmosphere Tube Furnace: Double-walled air-cooled shell, optional 10-type multi-atmosphere system, integrated vacuum quenching, full-process material heat treatment. Applications: powder materials, ceramics, metallurgy, electronics, glass, chemicals, machinery, refractories, new materials, etc.
