Introduction
This tube furnace for wafer processing is designed for sample preparation of various materials in a clean environment. The product uses a ring-shaped heating element outside the high-purity quartz vacuum chamber for uniform heating. It features high thermal efficiency, fast heating rates, and excellent temperature uniformity. The protective atmosphere circulates evenly inside, with forward and reverse flow, and high-temperature resistant seals are used at sealing points. The water-cooled stainless steel sealing system ensures safety and reliability.
The equipment is equipped with a complete automated touch-screen interface and includes over-temperature, thermocouple disconnection, and low water pressure alarm functions.
Main Features
- Large-diameter quartz vacuum chamber, capable of handling large-sized, thin sheet-like samples, with uniform heating from the ring-shaped heating element, ensuring excellent sintering results.
- Embedded operating system with a bilingual (Chinese/English) graphical interface, featuring a 7-inch color touch screen for intuitive operation and real-time curve tracking.
- Double-layer insulation structure with a wind-cooling interlayer.
- High-purity Al2O3 fiber refractory insulation material for maximum energy saving.
- High-purity alumina coating on the refractory furnace lining to extend service life.
- High-purity quartz furnace plug helps establish custom temperature gradients inside the tube.
- Complete over-temperature, thermocouple disconnection, and cooling water failure protection measures for safe operation.
- Interchangeable temperature measurement hole and observation window (select one).
Precautions for Equipment Use
1.The gas cylinder has a high internal pressure. When introducing gas into the furnace tube, a pressure reducing valve must be installed on the cylinder. It is recommended to select a small pressure reducing valve for experimental use, with a pressure range of 0.01MPa-0.15MPa, ensuring more accurate and safe operation.
2.When using this equipment for high-temperature sintering, a water chiller must be connected to the system to prevent the high-temperature sealing silicone rings from melting during operation.
