FAQ
Q1: What is the maximum operating temperature?
A: Standard rings operate at 1,100°C continuously, with short-term tolerance to 1,450°C (custom high-purity grades available).
Q2: Can you manufacture custom shapes/sizes?
A: Yes – we provide CNC-machined rings with tight tolerances (±0.5mm). Send your specifications for a quote.
Q3: How should I clean quartz thermal insulation rings?
A: Recommended methods:
1) Acid Cleaning: Soak in dilute HNO₃ or HCl (avoid HF)
2) Thermal Cleaning: Heat to 800°C for 2 hours
3) Ultrasonic Cleaning: For particle removal (alcohol-based solutions)
Q4: What is the lead time for orders?
A: It depends on order quantity.
