Frequently Asked Questions
What is the benefit of the 13-zone temperature control?
Multizone control allows for a highly customized heating and cooling curve. This is vital for complex ceramic recipes that require different soak times and temperature gradients to achieve optimal grain growth and densification.
Why are ceramic rollers used instead of metal?
At temperatures of 1000°C–1100°C, metal rollers can oxidize and release metallic contaminants into the kiln atmosphere. High-purity ceramic rollers eliminate this risk, ensuring the electronic properties of the components remain uncompromised.
How does the atmosphere system manage high-purity Nitrogen?
The furnace is equipped with advanced sealing and gas flow controls that maintain a stable positive pressure of high-purity Nitrogen. This prevents oxygen ingress, protecting sensitive electrode materials from oxidation during the sintering phase.
Is this furnace suitable for continuous 24/7 operation?
Yes. The modular structure, heavy-duty Silicon Carbide rods, and robust transmission system are designed specifically for high-capacity, continuous industrial production environments.
What is the maximum operating temperature and control precision of the furnace?
The furnace achieves a maximum temperature of 1100°C (with a stable operating temperature of 1000°C) and features a high control precision of ±1°C to ensure stable processing.
What are the power requirements and average holding power?
The system features a maximum heating power of 279 kW for rapid thermal response and maintains an energy-efficient holding power of approximately 140 kW during operation.
