A customer once asked me, ‘Do you have any customized large-size silicon carbide ceramic filters for pouring heavy castings? ‘ The heavy castings mentioned by the customer here refer to 25MT nickel-aluminum bronze marine propellers (NAB).
But unfortunately, we told our customer that silicon carbide ceramic foam filters are mainly used for small castings, the maximum can only be a few hundred kilograms, so 25MT nickel-aluminum bronze marine propellers cannot use it.
So what can silicon carbide ceramic foam filters be used for? Can it be used in copper casting applications? If so, how can it be used in copper casting? Let us introduce it in detail below.
What is Silicon Carbide (SiC) Ceramic Foam Filter?
Silicon carbide (SiC ) ceramic foam filters are advanced porous ceramic filters used in the metal casting industry to improve the quality of castings by removing impurities and non-metallic inclusions from molten metal.
Here are some specific details about SiC ceramic foam filters:
- Material Composition: SiC ceramic foam filter is mainly composed of silicon carbide (SiC) slurry and polyurethane organic sponge. SIC material is known for its excellent thermal stability, high-temperature resistance, and chemical inertness.
- Pore Structure: The foam-like structure of these porous ceramic filters consists of interconnected pores of controlled sizes. This structure allows molten metal to flow through the filter while capturing and retaining impurities and non-metallic particles.
- High-Temperature Resistance: Silicon carbide ceramic foam filters have a remarkable temperature resistance of up to 1560°C, making them suitable for use in high-temperature casting processes involving metals like copper, aluminum, and iron.
- Filtration Efficiency: These filters effectively remove impurities such as oxides, slag, dross, and other contaminants from molten metal, leading to cleaner and higher-quality castings with improved mechanical properties.
- Application: Silicon carbide foam ceramic filters are commonly used in the casting of various metals where high purity and quality are essential. They find applications in industries such as automotive, and aerospace manufacturing.
- Benefits: By using silicon carbide foam ceramic filters with high-temperature resistance, foundries can achieve better casting results, reduce defects, enhance the surface finish of castings, and improve the overall quality of metal components.
- Durability: The robust nature of silicon carbide allows these filters to withstand the harsh conditions of metal casting processes, ensuring long-lasting performance and reliability.
Overall, silicon carbide ceramic foam filters with a temperature resistance of up to 1560°C play a crucial role in enhancing the quality, purity, and integrity of metal castings, making them an indispensable tool in the metal casting industry.
Application of Silicon Carbide Ceramic Foam Filter in Copper Casting
We have learned about silicon carbide ceramic foam filters and know that silicon carbide ceramic foam filters can be used for copper casting. So, what kind of copper castings can it be used for?
Here are some specific copper castings where silicon carbide ceramic foam filters can be applied:
- Copper Pipes and Tubes
- Copper Alloy Castings
- Copper Pump Components: Such as impellers, casings, and shafts
- Copper Automotive Parts: Silicon carbide foam ceramic filters are beneficial in casting copper automotive parts like bearings, gears, and connectors
By using silicon carbide foam ceramic filters in the casting process of these copper components, foundries can enhance the quality, mechanical properties, and reliability of their products.
