Casting Nozzles

Casting Nozzles

For purposes of supplying molten aluminum to a continuous caster. A casting nozzle is used to have a tip which extends into the casting rolls. AdTech provides a casting nozzles design that provides uniform flow across the direction of flow to avoid non-uniform freezing and surface defects.

Traditional Refractory Nozzles

The traditional refractory nozzles exhibit good thermal insulation and low heat capacity, it is not very homogeneous in terms of chemical composition and mechanical properties. In addition, it adsorbs moisture and is subject to embrittlement or low mechanical strength upon preheating to operating temperature which allows such nozzles to be used only once. Further, such materials frequently outgas and experience cracking upon heating, both of which are undesirable characteristics for successful caster nozzle performance. Refractory materials used to fabricate the casting nozzles have not been satisfactory for other reasons. For example, often the refractory material is reactive or subject to erosion or dissolution by the molten metal, e.g., aluminum, being cast, and this results in particles of refractory or reaction products ending up in the cast product.

AdTech Casting Tips and Nozzles

The AdTech casting tips and nozzles design which employs molten metal flow controllers to ensure uniform flow across the direction of flow of molten metal through said tip. It is a novel material resistant to erosion or dissolution by molten metals such as molten aluminum, the material having low thermal conductivity and low thermal expansion. Caster tips have been fabricated from various refractory materials. It is made of nano-grade fiber composite material and used for crystallization and size control of aluminum foil casting. It features fiber uniformly distributed, proper density, good insulation, accurate size, good inoxidizability, layer stout, Non-deformation. Can protect foil surface. To paint BN is recommended.
