Features
- Cold Wall Vacuum furnace design with stainless steel jacket with baffled water cooling.
- Operation to 2500°C. Temperature uniformity to ± 5°C in effective hot zone.
- Vacuum Load locks on entrance and exit tunnels to isolate the chamber during boat loading and unloading.
- PLC with Industrial Programmable Controller or PC system using Intellution™ FIX32 HMI software customized by Centorr/Vacuum Industries for continuous furnaces, with extensive data acquisition, and remote operation capabilities.
- Operation in Inert gas, Hydrogen Process gas, or vacuum environment.
- Two-sided or four-sided graphite heating elements and durable Graphite Board insulation for long hot zone life.
- Cold wall design offers rapid heat up and cool down times (2-3 hours from RT - 2200°C) compared with 3-5 days for heat-up/cool-down of refractory hot wall units.
- Large cycle time reduction translating to excellent throughput. Typical 15 hr "door-to-door" batch furnace cycles can be reduced to 2-4 hr continuous furnace cycles with improved quality.
- The smaller work cross section in a continuous furnace offers minimal thermal inertia compared to large batch furnaces, shortening cycle times.
- Semi-Continuous pusher action or intermittent push designs.
- System designed for quick and easy access to the furnace hot zone for repairs and preventative maintenance.
Materials Processed
- SiC, Si3N4
- Carbon-Carbon Composites
- Tungsten Carbide
- MIM components
- BN, ALN
- Alumina
- Tungsten Powders
Optional Features
- CE / VDE / TüV / CSA approvals and other non-U.S. standards for compliance.
- Rigid or Flexible water cooled busswork for improved maintenance and best electrical efficiency.
- Manual rotameter or Mass Flow Controllers for precise, repeatable gas flow.
- Optional Binder Removal System consisting of thermal oxidizer in dedicated debind zone with inner retort designed for durability, ease of replacement and low cost for efficient binder removal.
- Automatic loading and unloading conveyor system with optical proximity switch sensors for notification of work boats exiting the furnace.
- Cold wall designs allows for rapid cold starts, zone temperature adjustments, and fast cool downs providing more flexibility in production planning, product changeover, maintenance planning, and troubleshooting.
- Entry and Exit Load Locks result in safe operation in an inert gas/vacuum environment and reduce the customer's process gas costs compared with systems that flow inert gas out the entrance/exit. tunnels (Process gas requirements are now limited to the amount required to ensure the proper reactions with the raw materials).
