Vertical Vacuum Pyrolysis Furnace

Vertical vacuum pyrolysis furnace is used for vacuum pyrolysis sinter process of ceramic-matrix composite material.

Technical Features
1. The vacuum pyrolysis tube furnaces have sealed high temperature pyrolysis chamber, great contamination proof feature and easy maintainence.
2. For large size furnace, it will be designed to multiple temperature control zones to improve the temperature uniformity.
3. It is equipped with external rapid cooling system to shorten the production cycle.
4. Multiple stage exhaust gas treatment system is adopted to handle the tar, dust and gasses.

Optional Configuration of Vertical Vacuum Pyrolysis Furnace
1. Furnace door: Hydraulic lift/mechanical lift, swing open/parallel open (large size door), Manual tight/Auto lock-ring tight
2. Furnace vessel: All carbon steel/Total stainless steel
3. Furnace hot zone: Refractory brick + Ceramic fiber
4. Heating element and muffle: Graphite/C/C composite material
5. Process gas system: Volume/mass flow-meter, Manual value/auto value, Foreign brand/Chinese brand
6. Vacuum pump and gauge: Foreign brand/Chinese brand
7. HMI: Simulation screen/Touch screen/Industrial personal computer
8. PLC: OMRON/Siemens
9. Temperature controller: SHIMADEN/EUROTHERM
10. Thermocouple: W-Re type/S type /R type
11. Electric components: CHINT/Schneider/Siemens
