Caratteristiche del prodotto
- Dual-configuration quartz glass furnace tubes (standard and specially shaped); supports both vacuum and controlled-atmosphere sintering
Equipped with one high-purity quartz tube (D150×600mm) and one specially shaped quartz tube (80mm diameter at ends, 150mm in the middle) designed specifically for vacuum and gas-flow sintering. The sealing flanges for the shaped tube are made of stainless steel and feature two gas inlets, one gas outlet, and one vacuum port, meeting the requirements for vacuum and various atmosphere sintering processes.
- Mechanical bearing-driven rotation and electric tilting for uniform material heating
The furnace tube utilizes a mechanical bearing drive system for automatic rotation at an adjustable speed of 0–5 rpm. The tilt angle is electrically adjustable from 0° to 15°. The combination of rotation and tilting ensures continuous material tumbling and uniform heating, making it ideal for the consistent sintering of powder materials.
- Independent temperature control for dual zones; adjustable constant-temperature zone length
Features two independently controlled temperature zones, allowing the length of the constant-temperature zone to be adjusted to meet process requirements. Temperature control accuracy is ±1°C, and furnace temperature uniformity is ±3°C (depending on heating chamber dimensions); S-type thermocouples provide a measurement range of 0–1600°C.
- Dual Sevenstar mass flow controllers; compatible with multiple gases
Equipped with two Sevenstar mass flow controllers (0–5 L/min) compatible with gases such as nitrogen, Argon, and oxygen. Precise control of the two gas inlets enables sintering under various atmospheric conditions.
- Digital vacuum gauge and two-stage vacuum pump; controllable slight positive pressure
Equipped with a direct-drive two-stage vacuum pump (2 L/S) and a digital vacuum gauge (-100 to 100 kPa). The system supports not only vacuum operation but also sintering under slight positive pressure, meeting the specific pressure environment requirements of specialized materials.
6. Magnetic fluid sealed rotary joint for reliable sealing
The flanges at both ends of the intermittent sintering furnace tube are made of 316L stainless steel, and the rotary joint utilizes a magnetic fluid seal, ensuring excellent vacuum/atmosphere sealing performance even while the tube is rotating. It is equipped with a PTFE (Teflon) feeding pusher to facilitate material loading.

Centralized control is provided via a 7-inch touchscreen and Siemens PLC, allowing for the configuration of heating profiles for each segment and the simultaneous control of two gas lines. The system features 30-segment program control, enabling precise heating and cooling rate adjustments, as well as programmable commands such as jump (looping), run, pause, and stop.
