A critical aspect of high temperature furnace operation is temperature control and uniformity. Advanced furnaces are equipped with PID (Proportional-Integral-Derivative) controllers, thermocouples (like Type S, R, or B), and digital interfaces that ensure accurate and consistent thermal profiles. Uniformity across the heating chamber is essential for applications like sintering, where temperature variations can result in material defects or incomplete bonding at the microstructural level.
Safety considerations are paramount when dealing with high temperature equipment. Furnace designs incorporate thermal cut-off systems, cooling jackets, interlocks, and flame or arc detection systems to protect users and components. Proper training, regular maintenance, and adherence to safety standards such as ISO and CE certifications are vital for preventing accidents and equipment failures.
Some of the important characteristics of these high-temperature furnaces are:
The maximum operating temperature is 1700 °C.
Heating is provided from both sides through vertically mounted SiC rods.
The SiC rods are controlled by a thyristor controller, which counteracts the aging process of the heating elements.
The swing door is provided with a hinge.
Multi-layered insulation for better performance.
For better ventilation, Dual shell housing is provided.
Lined with lightweight refractory bricks.
Motor-driven exhaust is provided on the furnace roof along with exhaust gas piping.
These High-Temperature Furnaces are completely automated and run on SCADA systems with PLCs to control the entire system, along with documentation and monitoring.
High-temperature accuracies with long heater life and refractory life are a feature of these Furnaces.
