Rotary Furnace

Rotary furnace is mainly used for metal salt calcination and metal oxide reduction process, such as APT calcination, blue tungsten reduction, etc.

Technical Features
1. The rotary reduction furnaces use rotary tube which will result in good powder fluidity.
2. The intermittent loading and unloading type assures good sealing performance and low gas consumption with gas recycling.
3. Full automatic loading and unloading is available, which assures stable product quality and low labor force.
4. Furnace has the functions of remote control operation, remote malfunction diagnosis and remote program update functions.

1. Refractory material: silicate aluminum fiber/alumina ceramic fiber/high alumina brick
2. Heater material: 0Cr21Al6Nb, 0Cr27Al7Mo2
3. Tube material: SUS304/SUS310S/RA330/RA600
4. Sealing type: fill sealing/graphite+metal sealing
5. Loading type: vacuum feeding/vibration feeding/manual feeding
6. Operation panel: simulation screen/touch screen/industrial computer
7. PLC: OMRON/Siemens        
8. Temperature controller: SHIMADEN/EUROTHERM
9. Thermocouple: C type/S type/N type
10. Recorder: Paperless recorder/paper recorder, Foreign brand/Chinese brand
11. Electric components: CHINT/Schneider/Siemens
