High alumina silicate Al-Si ceramic fiber casting nozzle board & caster tip for aluminum strip casting
Caster tip is made of advanced aluminium silicate ceramic fiber and high temperature adhesive,it is mainly used in continuous , semi-continous casting and rolling production line.
We can produce different types and specifications according to customer's drawings and requirements.
1. Excellent heat preservation.
2. High strength of anti-flex and anti-pressure.
3. Excellent thermal shock resistance.
4. Smooth surface, non stick aluminum.
5. Good insulation, non-deforming.
6. Precise dimensions, easy to adjust the roll gap.
