A typical furnace system consists of the following:
- Basic Furnace Chamber Assembly
- Heat Zone Assembly
- Chamber with frame
- Sight Window
- Process Gas System
- Evacuation System
- Power Supply System
- Temperature Control Instrumentation.
Basic Furnace Chamber Assembly
The Basic Furnace Chamber Assembly includes the Furnace Chamber which is fabricated of 316 S/S and is built and stamped to ASME code. The High Pressure Chamber is the water‐cooled Inner Chamber which contains the fibrous graphite insulation and the graphite heating element. The furnace cover is raised and lowered manually. A sight port is provided at the front of the chamber in line with the Heat Zone center. Ports are also provided for thermocouple, for process gas inlet and outlet, for evacuation, and for gauges.
Process Gas System
The Process Gas System consists of the evacuation pump with the manifold, trap, valves, pressure gauge, gas pressure controller‐indicator, vacuum gauge, pressure relief, and panel mounted controls.
Power Supply System
Power Supply Systems consist of Silicon Controlled Rectifier Power Controller with Current Limit, Stepdown Transformer, Circuit Breaker, Contactor, Control Transformer, Ammeter, Voltmeter, Pushbuttons, Indicator Lights, Water Interlocks, all completely wired and packaged in a floor standing cabinet.
Temperature Control Instrumentation
Centorr Vacuum Industries can supply from the simplest Manual Power Control to the most elaborate instrumentation. This particular furnace is usually supplied with a Digital Control Programmer (Microprocessor) working in conjunction with a W/Re thermocouple and an optical pyrometer. A panel mounted switch permits switching from thermocouple to power transducer mode.
