Aluminium Titanate Ceramic Stalk/Riser Tube

The aluminium titanate ceramic stalk/riser tube replaces conventional cast iron or common refractory riser tubes and is impervious to penetration in molten aluminium and highly corrosion-resistant, providing a longer service life compared to conventional materials. It is less likely to stick to aluminium and reduces slagging on the tube wall, making routine maintenance easier while reducing downtime losses.

Advantages and Features:

• Application Scenario: The thermal insulation performance of the riser in differential-pressure and low-pressure casting is directly related to the defect rate of castings. Among the available materials, aluminium titanate ceramic becomes the ideal riser material because of its various advantages.
• Low Thermal Conductivity: The low thermal conductivity and non-wettability of aluminium titanate can effectively reduce the slag formation in the upper part of the riser, ensure the filling degree of the mold cavity and improve the quality stability of the casting.
• High Shock Resistance: Compared with cast iron, carbon-nitrogen and silicon nitride, aluminium titanate has better shock resistance, so it can avoid preheating treatment before installation and reduce the labor intensity of workers.
• Impermeability: In several commonly used aluminium water immersion materials, aluminium titanate and aluminium water have better non-wetting, can be exempted from coating agents and there is no pollution to aluminium water.
