Typical Furnace Specifications
| Performance Characteristics | Operating temperature: to 2200°C in a full atmosphere of nitrogen or 1900°C in a full atmosphere of hydrogen gas. |
| Vacuum Chamber | Stainless steel interior, fully water jacketed (carbon steel) with baffles for uniform coolant distribution. Full opening, fully jacketed and baffled doors at each end. |
| Hot Zone | Elements: Rugged molybdenum or tungsten rod elements arranged in uppoer and lower banks with power independently adjustable to provide optimum uniformity; surround work on four (4) sides. |
| Thermal Insulation | Heat shields retained in removable stainless steel frame. Work Support: 1/4" x 2" hearth rails mounted in posts firmly supported at chamber. |
| Dew Point Control System | Stainless steel bubbler with thermostat control and electronic water level control. Dew point level is controlled by blending wet and dry gas. Gas lines are heat traced to prevent condensation. Varying dew points are automatically programmed with a DSP700 programmer/controller, hygrometer, and automatic valves. |
| Hydrogen System | Model G10503A flow through process gas system, contains extra door clamps, pressur relief ports, automatic purge system, and necessary interlocks for safe operation. |
| Pumping System | Mechanical pump with manifold, automatic valve. |
| Power Supply | Variable reactance type with 3-phase input, trimming for upper and lower element banks. Rigid, water-cooled buss connection to furnace electrodes. |
| Controls and Instruments | NEMA-1 cabinet containing microprocessor-based programmer/controller (Honeywell DCP700). Data logger for temperature and pressure (Honeywell DPR1500). Over-temperature protector with separate type W5 thermocouple. Ammeters and voltmeters for each power supply output phase, push-buttons and pilot lights, alarm panel for safety interlocks on all critical circuits. |
| Utility Requirements | Electrical: 460/3/60 Water: 30-50 psig; 60-70°F Compressed Air: 80-100 psig, filtered and lubricated. |
| Accessories | Fork lift load truck, manual operation with electro-hydraulic lift, guides and stops on truck and furnace. |
