Latest Patents

Sueli's latest patents include a method for the production of a refractory filter. This method involves creating closed edge filters suitable for filtering molten metal. The process begins with providing a reticulated foam substrate that has at least one first surface for forming a side face of the filter and two opposed second surfaces for forming the through-flow faces of the filter. A liquid comprising an organic coating component is applied to the first surface, which is then solidified to form a filter precursor. This precursor is impregnated with a slurry containing particles of a refractory material, a binder, and a liquid carrier. Finally, the impregnated filter precursor is dried and fired to create the finished filter.
