Application
With high quality forsterite as original material,this product is treated by special process and prepared through scientific formula.
Characteristics
Since the high melting point and not prone to be wet when contract with water,this filling materials possess several advantages such as preventing sinter and steel seeping,high casting rate and non-contamination to liquid steel.
Cautions
1.Rainwater proof and moisture proof for storage and transportation.
2.The product should be dried completely before used.
3.Package is done by use of ton-bags,or small bags of 20kg/bag and 30kg/bag or under the customer's requirements.
