Frequently Asked Questions
Q: What is the primary advantage of using dry vibration material over traditional casting?
Dry vibration material offers simplified construction, significantly reduced labor intensity, and creates a denser structure that extends the tundish service life to over 35 hours.
Q: How does this material affect the quality of the steel billets?
The material maintains a very low tundish slagging rate, which helps in purifying the liquid steel and improving the overall chemical and physical quality of the steel billets.
Q: What are the available packaging options for international shipping?
We offer flexible packaging: 1-ton Jumbo Bags, or 10kg and 25kg small bags within Jumbo Bags. Custom packaging is also available upon request.
Q: Why is the baking temperature critical for the tundish wall?
After red baking, the wall must not be cooled down rapidly to avoid a loose cladding structure, which ensures the material maintains its intended performance and erosion resistance.
Q: Which ports do you typically use for export deliveries?
Our standard delivery ports in China are Xingang Port and Qingdao Port, ensuring efficient logistics for global shipments.
Q: What is the difference between Magnesia and Magnesium Siliceous vibrating materials?
Magnesia material has higher MgO (≥75%) and higher bulk density (≥5.0 g/cm³), whereas Magnesium Siliceous material contains more SiO2 (≥20%) and has a lower bulk density (≤2.5 g/cm³), allowing for different thermal expansion requirements.
