FAQ
Q: What is the typical service life of a graphite casting ring?
A: Die life depends on casting material, temperature, casting speed, and cooling. For copper tube casting, typical ring life ranges from 50 to 200 tons of cast product. Proper cooling, lubrication, and operating parameters are essential for maximizing die life.
Q: Can you produce shaped dies for non-round profiles?
A: Yes, we specialize in custom graphite dies for various casting profiles including tubes, rods, bars, and custom shapes. Please provide your casting cross-section drawings, and we will manufacture precision dies to your exact dimensions.
Q: What graphite grade is best for continuous casting?
A: Fine-grain isostatic graphite with high density and hardness provides the best combination of wear resistance and surface finish for continuous casting. Our technical team can recommend the optimal grade based on your specific casting material and production requirements.
