Aluminium Casting Tips

Aluminium Casting Tips

During the casting and rolling process, the melt flow in the cavity is required to be stable, and the melting heat flow field at the nozzle outlet is uniformly distributed in the width direction, so the shunt blocks must be reasonably distributed. Aluminium casting tips are the key components of high-speed thin strip twin-roll casting, and they directly affect the quality of the aluminum plate.

High-speed thin strip twin-roll casting is a short-flow near-net shape processing technology. The casting-rolling process belongs to the sub-rapid solidification category, and its cooling rate is between 102°C/s and 104°C/s.

This technology particularly has the advantages of refining crystal grains and suppressing segregation, can improve the microstructure of the product, bring excellent subsequent processing performance, and can produce products that are difficult to produce under conventional process conditions.

Due to its technical characteristics, this technology requires rapid cooling of molten metal during casting and rolling, and a reasonable flow field in the nozzle cavity, otherwise it will lead to the quality of thin strip products and the stability of castings and castings. The rolling production process is difficult to guarantee.

The structure and components of the nozzle cavity are the key components that affect the flow field and temperature field distribution in the nozzle cavity. Therefore, it is necessary to develop a new type of mold nozzle, which has a stronger cooling capacity and a more reasonable flow field distribution in the nozzle cavity.

Aluminum Casting Nozzles

The aluminium casting tips are made of ceramic fiber and other refractory materials. The opening surface and the working surface are coated smoothly, which can resist the corrosion of liquid aluminum and ensure the purity of the aluminum plate.

Caster tips have excellent non-wetting properties, low thermal conductivity, high-temperature stability, uniform density, smooth surface, and close tolerances, and are high-quality products for continuous aluminum strip casting.

The casting tips and nozzle are composed of ceramic fibers and inorganic ceramic materials, and have the advantages of moderate elasticity, small deformation, and long service life.

It can effectively prevent the molten aluminum from corroding the nozzle cavity of the casting mold, thereby providing an effective guarantee for the quality of the cast-rolled aluminum plate.

According to customer requirements, feed tips and nozzles of various types and supply methods can be manufactured.
