Dry Material for Tundish
1.Product properties and features
Dry vibrating material is made from new-type low carbon and environmental protection bond after optimizing the raw material and agglutinant. Low baking can be conducted just below 200℃ after construction and the service life can exceed 40 hours. It is easy to turn package after usage, which is especially suitable for working linings whose teeming and steel pouring time is too long or whose tundish has a quick-change water gap.
