Product Description
Zirconia Ceramic Foam Filters are specially designed for filtering various types of steel, including unalloyed, low-alloyed, stainless, and high-alloyed steels. These filters are highly recommended for high-quality alloys due to their excellent resistance to corrosion and molten steel attacks. zirconia ceramic foam filter significantly improve the filtration process by effectively removing inclusions, reducing trapped gases, and creating laminar flow. The result is cleaner filtered metal, which leads to better-quality castings, reduced scrap, and fewer inclusion defects.
These filters are ideal for use in steel casting filtration, specifically for steel alloys that require high temperatures of up to 1700°C. They are particularly recommended for high-quality alloy grades. By utilizing these filters, casting qualification rates improve, the metallographic structure enhances, and they are suitable for investment casting after preheating. Zirconia ceramic foam filters are the optimal choice for producing high-quality steel products with superior filtration capabilities.
