HTBLF-1700-A larger box furnace is a bottom loading furnace (216 Liter capacity) with inert gas atmosphere control up to 1700 ºC. The furnace consists of high-quality alumina fiber bricks and Molybdenum alloy heating elements with 600 x 600 x 600mm heating chamber. A vacuum-sealed steel chamber with a water cooling jacket as well as the vacuum & gas flow control system enables material processing under inert gas atmosphere.
Furnace Structure | Double-layer stainless steel structure for maximum safety The bottom loading mechanism by electric hydraulic lift ， which can hold 200 Kg Max. sample Water cooling front door and sealing jacket for max. service life. Touch-screen digital control panel for all parameters. Precision temperature control with +/- 3ºC uniformity inside the chamber and +/-1°C accuracy. |
Inside Chamber Size | Heated chamber: 600 x 600 x 600 mm (216 Liter capacity) Energy-saving 1800-grade fibrous alumina insulation. High-purity Al2O3 coating. |
Power | AC 460V， three-phase; 50/60 Hz 50 KW 63Amp （ 100Aair-breaker） |
Heating Element | 12 Pcs Mo heating element |
Continuous Working Temperature | 1600°C |
Maximum Working Temperature | 1700°C (< 1 hr) |
Heating Rate | 5°C / min |
Temperature Accuracy | +/- 0.5°C |
Thermocouple | two B-type thermocouples (control thermocouple and secondary alarm thermocouple) |
Temperature Control | Eurotherm controller with PID automatic control via SCR (Silicon Controlled Rectifier) 30 programmable segments for precise control of heating/cooling rate and dwell time. Over-temperature protection and thermocouple failure alarm functions allow operation without attendant(s). +/- 0.5ºC temperature accuracy. RS485 Communications Port |
Gas Flow Control and Vacuum Valve | Two flow meters (#1: 0~8L/min; #2: 0~4L/min) are installed on the front panel of the furnace. One heavy-duty vacuum pump (CE certified) is built on the bottom of the furnace. |
Water Cooling | A 16L/min recirculating water chiller is installed in the bottom of the furnace for cooling the furnace sealing flange (CE certified only) ISO CE Certification for water chiller is available upon request at extra cost, please contact our sales representatives for a quote. |
Net Weight | 3000 Kg |
Warranty | One-year limited warranty with lifetime support. (Consumable parts such as sample plates and heating elements are not covered by the warranty, please order the replacement at related products below.) |
Compliance | CE Certified for the furnace, vacuum pump, and water chiller. NRTL (UL61010) or CSA certification is available at extra cost. |
Application Notes | For longer furnace life furnaces, we recommend the heating rate not to exceed 5 °C /min. The cooling rate shall also not exceed 5 °C /min. Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating. The refractory block must be inserted before closing door. Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. |
Warnings | ATTENTION: Any damages caused by the use of corrosive and acidic gasses are not under the coverage of One Year Limited Warranty. In order to prevent oxidation/corrosion damages to the Mo heating elements, it is necessary to keep a constant inert gas (Ar preferred) flow throughout the entire process. This is the most effective way to carry out any by-products. |
