Silicon Carbide

The superior dimensional tolerances of SELEE® Silicon Carbide filters for iron filtration are recognizable at first glance. These filters are precision-cut after firing to the tightest dimensional tolerances in the world. All surfaces, including the cut sides, have the desirable open-pore structure of true ceramic foam. The high internal surface area of this structure makes for a deep-bed filtration effect throughout the thickness of the filter. Through deep-bed filtration, even highly fluid slag is retained in the foam network, significantly reducing scrap and machining. SELEE produces Silicon Carbide filters in a wide variety of sizes and in several thicknesses and pore sizes to meet the filtration requirements of grey and ductile iron foundries.
