Tundish Vibro Mass
Tundish Vibro Mass
Tundish dry vibration mix is widely adapted and promoted in carbon steel making. Magnesia dry vibration mass is characterized by long life, easy to turn package and low labor intensity. Even though it has high construction requirements, long construction time and some other shortcomings, magnesia dry vibration mass has been widely promoted and applied in tundish.
We manufacture magnesite based moldable water-free mix for Tundish lining.
- It is easily filled between the permanent layer of Tundish and the steel former.
- The former is heated upto 300 C by a hot air generator for 2-2.5 hours, and then removed by crane after cooling.
- It is formed at designed thickness. It performs at long sequence lengths more than 20 hours and protects the quality of steel.
- Deskulling is a safe and quick process with our vibro mass, reducing downtime and lowering maintenance costs. It can be used in both cold and hot tundish practices.
