Micron-sized filter sheet with enriched aluminum melt inclusions and preparation method of micron-sized filter sheet
The invention discloses a micron-sized filter sheet with enriched aluminum melt inclusions and a preparation method of the micron-sized filter sheet. The micron-sized filter sheet comprises a porous SiC ceramic sheet, the aperture of the porous SiC ceramic sheet is 10-60 [mu] m; the periphery of the porous SiC ceramic sheet is sprayed and blocked with a ceramic refractory material, and a filtering part which is not sprayed and blocked with the ceramic refractory material is reserved in the center of the porous SiC ceramic sheet; the upper end face and the lower end face of the filtering part are circular, and the connecting line of the circle centers of the two circles is perpendicular to the porous SiC ceramic chip; the through hole rate in the effective filtering area of the filtering part is larger than or equal to 85%. By means of the filtering part with the surface reserved with the round hole structure, quantitative analysis on impurities of the enriched aluminum melt in the later period and positioning of later sampling are facilitated; the filtering pressure of the molten aluminum is increased through the big-end-up variable diameter of the filtering part, so that pure molten aluminum can pass through an effective filtering surface more easily; the capacity of enriching aluminum melt impurities of the filter is effectively improved by limiting the aperture and the through hole rate of the filter.
本发明公开了一种具有富集铝熔体夹杂物的微米级过滤片及其制备方法，包括多孔SiC陶瓷片；所述多孔SiC陶瓷片的孔径为10‑60μm；所述多孔SiC陶瓷片的四周喷堵陶瓷耐火材料并使得多孔SiC陶瓷片中心预留出未喷堵陶瓷耐火材料的过滤部；所述过滤部的上端面与下端面均为圆形且两个圆形的圆心连线与多孔SiC陶瓷片垂直；所述过滤部的有效过滤面积内通孔率大于等于85％。本发明通过表面预留圆孔结构的过滤部便于后期对富集铝熔体杂质物进行定量分析及后期取样进行定位；通过过滤部上大下小的变径增大铝水的过滤压力，使纯净的铝熔体更容易通过有效过滤面；通过对过滤片孔径及通孔率的限定有效提高过滤片富集铝熔体杂质物的能力。
