1600°C double-door vacuum atmosphere box furnace, 3-zone MoSi₂ heating with energy-saving IGBT DC power supply, B-type thermocouple. Equipped with vacuum & gas inlet system, oxygen monitor and 6P chiller.
| External Dimensions | 200 × 110 × 180 cm |
| Furnace Power | 90 kW, using 3-zone heating method |
| Maximum Operating Temperature | 1600°C |
| Heating Method (Heating Elements) | Silicon-molybdenum rod heating, equipped with 36 heating elements |
| Supporting Systems | Equipped with vacuum system and gas intake system; 8 gas inlets at the lower part on both sides are integrated into one main pipeline, equipped with flow meters and valves; equipped with a 6P water chiller; equipped with an oxygen content detection system |
| Heating Method (Power Supply and Connection) | Heating adopts an energy-saving IGBT DC power supply, which causes no interference to the power grid (unlike traditional thyristor + dry-type transformer, which causes interference to the power grid). The heating rods are connected in pairs in parallel, ensuring that if one heating element is damaged during operation, only 2 heating elements will not generate heat, ensuring that the normal operation of the electric furnace is not affected |
| Temperature Sensors | Platinum-rhodium wire B-type thermocouples are adopted, with 3 temperature control thermocouples, effectively ensuring furnace temperature uniformity |
| Heating Rate | 1–10°C/min |
| Temperature Difference | ±1°C |
| Furnace Chamber Dimensions | Not less than 1500 × 500 × 600 mm |
| Shell | The steel skeleton is made of suitable section steel and steel plates selected according to mechanical principles, welded in a scientific combination. The overall structure is sturdy, firm, durable, and reliable. All welds are uniform and smooth, free of defects such as pores, slag inclusion, and lack of fusion |
| Furnace Body Appearance | Straight and aesthetically pleasing, free of wrinkles or unevenness |
| Furnace Body Shell Temperature | At the maximum furnace temperature, the temperature of the external metal shell of the furnace shall not exceed 60°C in summer and shall not exceed 50°C in winter |
| Furnace Chamber Insulation Materials | The innermost layer (high-temperature layer) of the furnace lining has a thickness of not less than 200 mm and uses imported zirconia polycrystalline fiberboard with a temperature resistance of 1800°C; the second layer of refractory cotton board is not less than 160 mm thick. The total thickness of the refractory cotton board is not less than 500 mm |
| Supporting Circuit Modification | Pure copper cables connected to the laboratory’s existing distribution box |
| Power and Power Consumption Monitoring | Add power and power consumption monitoring |
| Control System | Equipped with a 10-inch touch screen, capable of remote control; supports multi-person mobile phone monitoring; the electric furnace operation can also be controlled via mobile phone to start and stop, and view reports, curves, etc. |
