Tundish Lining Development History:
1) Before 1995,lining is Siliceous heat-insulating board,average service life 6hr,max.10 hr,service life short,poor erosion resistance, have pollution on tundish
2) After 1995,people replace the siliceous board by Magnesia calcium or magnesium coating as the tundish liner,the service life isincrease to 10hr,max about 24 hours,have purification effect of the ladle.but with heavily increase the demand on Mechanical spraying or manual labor daubing.
3) Since 2000, with the rapid development on Tundish rapid replacement technologies,the tundish service life had greatly improved,which will have more higher requirement on the liner.
The Liner Dry vibration mix the most important point is with high using life,and easy for firing, which is impossible to catch for other coating material.
