Following the clay and high alumina
brick, tundish insulation board, tundish coating, dry
vibration mix is the fourth working lining materials for tundish. Following
compare shows why dry vibration mix could replace the insulation board
successfully.
Insulation board, which is mainly used
in cold tundish (one without baking before being used), it devotes much for us
in energy saving and heat insulation. But, due to its fatal disadvantage, it is being eliminated quickly.
1. Bonded with many agent, insulation board add
silica and hydrogen under high temperature in steel liquid, reduce its purity,
produce harmful gas to hurt worker’s health. VS: Dry
vibration mix is
bonded without carbon, produce no sharp aroma, and greatly reduce avoid the
pollution for steel liquid and environment.
2. Short using life (for common steel, only 8 Hrs, for
Mn-alloy steel, only 4hrs). VS: dry
vibration mix usual
using life: 24 hrs min, when worked with the fast exchange nozzle, it could
reach average using life 45hrs.
3. Easy to be broken during transportation, once one
piece is broken, the whole set will can’t be work. VS: dry vibration is
premixed and packaged in waterproof jumbo, applicable for ship, truck, train,
air, etc long way transportation.
4. Low corrosion resistance, easy to make tundish
become leakage. VS: dry
vibration mix is made
by ramming, dense and stable, after sintering, form a protect layer with
tundish backing layer, could improve tundish using life and reduce spare
tundish number.
Therefore, should
you want to improve your tundish life, please do not hesitate to try Changxing
Refractory dry
vibration mix, 24 hrs
using life is waiting for you.
