KBF1700 Box-Type Furnace
• Product Name: KBF1700 Box-Type Furnace
• Model: KBF1700
Product Summary:
The KBF1700 box-type furnace utilizes an 1800-type silicon molybdenum rod as the heating element. It features a dual-layer shell structure and a YuDian programmable temperature control instrument with phase-shift triggering and thyristor control. The furnace chamber is constructed with German-imported alumina polycrystalline fiber material. The double-layer shell is equipped with a forced air cooling system, enabling rapid temperature rise and fall. This furnace offers advantages such as uniform temperature distribution, low surface temperature, fast temperature rise and fall rates, and energy efficiency. It is an ideal product for universities, research institutions, and industrial enterprises engaged in powder sintering, ceramic sintering, high-temperature experiments, and quality testing.
Heating Element – Silicon Molybdenum Rod:
• The hot end diameter (D1) of the silicon molybdenum rod is 7mm, which is generally thicker than the 6mm used by most manufacturers. This design resists bending, offers a low surface load, and ensures a longer service life.
• Utilizes heat bending technology for uniform resistance distribution and extended service life.
• The cold end length (Lu) is 210mm, and for a 400X300X300 furnace, it is 260mm (compared to the 180mm used by most manufacturers), resulting in a lower furnace top temperature.
• The surface of the silicon molybdenum rod is coated with a dense non-crystalline oxide film, which effectively protects the carbon rod.
Temperature Control Method:
• Utilizes YuDian programmable temperature control instrument.
• 30-stage programmable intelligent PID regulation.
• Equipped with over-temperature protection and open-circuit protection. The furnace's heating circuit automatically disconnects in case of over-temperature or open-circuit conditions. When the furnace temperature exceeds 1720°C or the thermocouple is burnt out, the AC relay in the main circuit will automatically disconnect. The ON indicator light on the panel will go out, and the OFF indicator light will illuminate, providing limited furnace protection.
• Equipped with power failure protection. When power is restored after a power failure, the furnace does not start heating from the initial temperature but rather resumes heating from the temperature at the time of power failure.
• The instrument features temperature self-tuning functionality.
