Advantages

  1. High strength, good elasticity, no deformation, long service life
  2. High precision, smooth surface, used for high-quality rolling
  3. Uniform fiber distribution, good insulation performance
  4. Wear resistance, high temperature resistance, erosion resistance, no slag;No chemical reaction with molten aluminium
  5. Strong carbonation resistance, complete specifications, comprehensive cost-effective.
  6. Self-produced fiber,strict quality control
  7. Automatic production line,high accuracy

Application

Used for aluminium foil, strip,sheet roll casting.

  • High temperature preheating is required to thoroughly dry the caster tips and low the thermal expansion.
  • Preheated by the baking box with circulatory ventilation is suggested.
  • Heating temperature 140 -180 ℃.
  • Preheating time:4 hours.
  • It should be used in time after preheating. Otherwise need to preheat again.
