Featuring "long-term temperature resistance at 1700℃" and "molybdenum disilicide rod heating", it achieves uniform temperature control of ±1℃, supports the introduction of multiple types of gases, and is equipped with water cooling, vacuum, and leakage alarm systems. It is suitable for high-temperature processing in scientific research and industrial applications, ensuring safety and high efficiency.
| Temperature | 1700℃ |
| Model | GWL-1700ZQLB |
| Power Supply (AC) | 380V |
| Maximum Operating Temperature | 1750℃ |
| Long-term Operating Temperature | 1700℃ |
| Control Range | 50 to 1700℃ |
| Temperature Measuring Element | Thermocouple with 分度 number (graduation number) B, measuring range 0-1820℃ |
| Installation Position of Heating Elements | Both sides (1800-type molybdenum disilicide rod heating elements) |
| Temperature Control Precision | ±1℃ (integrated circuit control, no overshoot) |
| Furnace Temperature Uniformity | ±1℃ (depends on the size of the furnace chamber; multi-point control can be adopted for large furnace chambers to achieve better temperature uniformity) |
| Heating Rate | Freely adjustable, with a range of 40℃/min (fastest) to 1℃/h (slowest) |
| Heating Elements | High-temperature 1800-type U-shaped molybdenum disilicide rods |
| Installation or Replacement of Heating Elements | The sealed top cover of the vacuum atmosphere furnace is designed with a mechanical lifting mechanism, which allows the sealed top cover to be lifted easily. After lifting, the entire top cover can be rotated, greatly saving labor and time. |
| Furnace Body | Processed by CNC machine tools, and manufactured through polishing, grinding, pickling, phosphating, plastic powder spraying, and high-temperature baking. It features a two-color design with a novel and attractive appearance, and has advantages such as oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Furnace Body Structure | Adopts an air-cooled double-layer structure to ensure a good working environment |
| Furnace Door Opening Method | Axial 180° side opening; the furnace door can rotate 360°, preventing the inner wall of the furnace door from scalding the arm when taking materials at high temperatures |
| Water Cooling System | Equipped with an imported hot water circulation pump and a circulation water tank. The imported hot water circulation pump can withstand hot water up to 160℃ and operate continuously for more than 1 year. The circulation water tank is made of 304 stainless steel. |
| Water-cooled Parts | Furnace mouth, furnace door, and furnace top of the inner furnace shell |
| Circulating Water Radiator | Uses multi-channel pure aluminum water circulation radiating fins, which greatly reduces the problem of excessively high water temperature |
| Vacuum Pump and Vacuum Degree | Adopts a two-stage direct rotary vane vacuum pump; vacuum degree: displayed as -0.1Mpa on the pointer pressure gauge |
| Pressure Resistance Performance | The furnace chamber steel plate of the electric furnace has a thickness of 6-20mm, adopts double-sided welding, and can withstand a positive pressure of 0.1Mpa |
| Gas Circuit Valves | Uses imported stainless steel valves |
| Pressure Detection | Equipped with 1 pointer pressure gauge with dual indication (positive pressure and negative pressure) (optional digital vacuum gauge, etc.) |
| Gas Flow Meters | 2 float flow meters (digital mass flow meters can be selected if the customer requires higher precision) |
| Pressure Protection System | Prevents dangers caused by closed furnace exhaust ports, blocked exhaust ports, or excessive furnace chamber pressure. Principle: Signals are obtained through an electric contact pressure gauge or pressure sensor, which drives the control module to close the electromagnetic gas inlet valve, start the electromagnetic exhaust valve and alarm, release pressure from the exhaust port, and trigger the sound and light alarm buzzer to ensure the normal operation of the electric furnace. |
| Gas Leak Alarm | Prevents leakage according to the introduced atmosphere. Function: When the gas leak alarm detects that the content of toxic or hazardous gases in the (indoor) air exceeds a certain level, it drives the module to shut down the electric furnace and gas source inlet, and open the exhaust port and exhaust fan, thereby creating a safer working environment (to be selected by the customer). |
| Applicable Atmospheres | Hydrogen, nitrogen, argon, carbon monoxide, oxygen, etc. |
