科瑞泡沫陶瓷过滤器具有规格齐全(尺寸:30-600mm,孔径:10-70PPI)、尺寸精确、强度高、比表面积大、孔隙率高、抗热震性强(90°)、在熔融金属中具有高温稳定性等特点。即使对1-10μm的微小杂质也有良好的吸附效果,不仅适用于高温熔融液体,还可用于气体除尘、隔音、催化剂载体基底等领域。
Ceramic foam filter sheets are advanced refractory filter materials with a three-dimensional open-pore structure, typically made from high-purity alumina, silicon carbide, or zirconia. Their uniformly interconnected pores effectively remove non-metallic inclusions from molten metal at high temperatures, improving melt cleanliness and casting quality.
During filtration, inclusions are intercepted and deposited on the pore walls while the molten metal flow becomes smoother, reducing turbulence, porosity, and inclusion-related defects.
