Casting Tips and Nozzles

CastingTipsAndNozzles NecoR3CastingTips


Casting tips, often referred to as casting nozzles or injectors, determine the width of the aluminium sheet during continuous casting. Casting tip sections, in conjunction with spacers, create a cavity allowing for the flow of metal through the casting tips just before solidification of the sheet.

Pyrotek Offerings

Mutiple design options are available in hard and soft tip variations. Pyrotek offers complete casting tip assemblies that are ready to insert into the casting tip base on arrival, thus eliminating any need to cut or assemble casting tips on-site.

Pyrotek's NECO R3 hard casting tips are specifically engineered and optimized for the production of high quality, aluminium continuous sheet casting for twin-roll Casters. NECO R3 material is a formulation of ceramic fibres bonded with an inorganic, silica binder. They are dimensionally stable, thermal shock resistant and do not cause outgassing. NECO R3 casting tips implement the highest standards in surface finish and leading edge cosmetics to ensure a smooth and consistent cast.

Pyrotek offers all of the component pieces required for continuous casting tip assemblies such as end dams, spacer boards, internal baffles, boron nitride coatings, Fiberfrax paper and glue for tip assembly.
