Magnesium/silicate dry vibrate mix
Refractories used for tundish working layer have magnesium & silicate dry vibrate mix, the former is suitable for small and medium sized tundish with short continuous casting time, the latter is suitable for large tundish with long continuous casting time.
Features of refractories used for tundishi working layer:
1, Convenient construction, mechanized operation, saving manpower and improving working efficiency.
2, Compact sintering, erosion and corrosion resistance, long service time
3, No pollution of molten steel which can meet the needs of clean steel continuous casting.
4, The working layer does not crack during use, easy to turn over the package.
